GHS Version 10.50 Update
New features, changes, and bug fixes since version 10.00
=========== MAJOR NEW FEATURES =========
Major Condition Graphics Performance And Appearance Improvements
DISPLAY STATUS produces report file output that is much smaller and prints
much faster than before, as well as higher quality. PDF output files are
6 to 20 times smaller. The previous behavior can be obtained using the new
PRINT /SLOW parameter.
DISPLAY STATUS now shows the exact outline of all shapes, instead of
approximating using the maximum width for indented shapes like bulbous bows.
DISPLAY STATUS legend box formatting is now much more reliable and compact.
DISPLAY STATUS reference point circles were made smaller and the waterline
shown on either side of the vessel were slightly extended for increased
visibility.
DISPLAY STATUS BODY @ section shows any critical points when they are located
longitudinally at the given section.
DISPLAY STATUS /SYNC[:ratio] and LOAD EDIT /CG[:ratio] optional subparameters
were added to specify the ratio of the height of the Condition Graphics
window to height of the main program window. If not present, a default
ratio of 1 is used, unless the main window is so wide that the CG window must
partially overlay it, in which case the CG window is reduced so it won't
unduly obstruct visibility of the main window.
CHANGE (tank) /COLOR:n parameter now specifies the tank's color in Condition
Graphics, overriding any CONTENTS /COLOR value.
New Condition Graphics Integration Within Existing Report Pages
DISPLAY STATUS writes to the end of the current report page if enough room,
so PAGE should be done prior to DISPLAY STATUS if a full page used only for
Condition Graphics is required.
DISPLAY STATUS /PAGE%:n parameter was added to restrict output to the given
percentage of the available print page. Subsequent DISPLAY STATUS /PAGE%:n
commands append to the same page if the total does not exceed 100% (and if
nothing else was written to the report in the interim). The /PAGE% parameter
can be omitted on the final DISPLAY STATUS command to fill out the remainder
of the page. The legend box is suppressed except for the final area on the
page; to skip the legend box entirely, use /PAGE% percentages that total less
than 100%.
New /EMAIL Parameter For Emailing Reports
COPY [attachfile...] /EMAIL[:toadr...] [/SUBject:"subject"] [/BODY:[@]body]
[/CC:ccadr...] [/BCC:bccadr...] was added to send emails via the default MAPI
mail server application using the specified TO/CC/BCC address lists, attachment
file list, subject heading, and body text. If the body begins with "@", then
the text is read from the specified body file (with CR separating paragraphs).
Email addresses are converted to lowercase unless enclosed in quotes, in which
case the form "Full Name <address@domain>" is supported.
PRINT [file] /EMAIL[:toadr...] was added to email the specified print file
(or current report file if blank) as a Preformatted Print File with ".PPF"
extension (which can be printed or previewed using the PRINT command).
Any COPY /EMAIL slash parameters may be used with the PRINT /EMAIL command.
New Support For Double-Clicking .RF, .GF, And .PF Files
Standard GHS installation assigns double-clicked documents with .RF extension
to run in GHS, with .GF extension to open in Section Editor, and with .PF
extension to open in Print Preview. The same behavior applies to extensions
with a single digit appended (so TEST.GF1 opens in SE32). Likewise .GFT
extension behaves like .GF, and .PPF extension behaves like .PF. To remove
these assignments, run UNREGTYP.EXE in your GHS program directory. To restore
these assignments if changed by some other application, run REGTYP.EXE in your
GHS program directory.
GHS main program command line transparently previews a print file ending in
".PF?" or ".PPF", and opens in SE32 a geometry file ending in ".GF?".
New Region-Aware Default Units And Date Format
UNIT default is Meters and Metric Tons outside the United States.
In metric units, the meters and centimeters abbreviations are now shown in lower
case.
REPORT default date format for page headers is controlled by the regional
options set in the operating system.
MESSAGE DATEFORMAT Year-Month-Day command was added to change the date format.
Year, Month, and Day can appear in any order, separated by "-", "/", or ".".
New Programmable KEY Footer Push Buttons
KEY command assignments are now shown at program startup as a collection of
push buttons in the footer, with each key's label on the button face and with
the button border only appearing when the mouse hovers over it. A footer
button's function key or control key shortcut can be seen by right-clicking it.
New HMMT WIND /BAND Method Accounting For Shielding
HMMT WIND /BAND[:bandwidth] [/COMBINE] offers an alternate method of deriving
wind heeling moments from the geometry.
The other HMMT WIND parameters /C1, C2, etc and /GUST can also be used
with the /BAND parameter. This method accounts for shielding between
components, and if the /COMBINE parameter is present it also accounts
for shielding between parts. It calculates the wind force using
horizontal bands. The wind pressure at the height of the center of each band
is applied. The band width may be specified, or the default 0.1 meter
(0.328 foot) may be accepted. Larger band widths reduce accuracy
but calculate more quickly. AXIS rotation is permitted.
Compared to the traditional non-band method in GHS (which takes lateral
projections of all components without consideration of shielding and applies
wind pressure at the center of each component), the band method has the greater
accuracy when there is overlapping of components in the wind plane. In typical
models where the ship's exterior is represented by several components, the
traditional method increasingly overstates the lateral area as the heel
angle increases. The accuracy of the band method is not generally affected
by the ship's attitude in either heel or trim. However the band method
does tend to overstate the wind plane area by approximately 5% at the
default band width setting.
A caching mechanism is now in effect for heeling moments derived from the
wind through the geometry. This increases the speed of righting-arm curve
calculations and the MAXVCG process.
New Damage Stability Support For Cargo And Passenger Vessels
Two additional variations of DAMSTAB /SDI are now available to implement
the SOLAS amendment MSC.194(80): /SDI194C for cargo vessels, and /SDI194P
for passenger vessels.
The full set of available parameters for the cargo version is,
DAMSTAB [(div list)] /SDI194C [/L: l1,l2] [/B: b] [/H: hmax]
[/STOP[:n]] [/DLL:loadline draft] [/MACRO:name] [/QUICK]
And for the passenger version,
DAMSTAB [(div list)] /SDI194P [/L: l1,l2] [/B: b] [/N: n1[,n2]] [/H: hmax]
[/STOP[:n]] [/DLL:loadline draft] [/MACRO:name] [/QUICK]
Only the final survivability is implemented. It is recommended that
survivability be computed using a macro (/MACRO parameter).
DAMSTAB /SIDE:Port|Starboard parameter was added to specify the side of damage
(for example, DAMSTAB /SDIC /SIDE:P). If not specified, the side having the
most tanks as listed in the DIVISION command(s) is used, or starboard if both
sides are equal.
DAMSTAB /SDI has a new parameter: /NOREQ which causes it to omit any
consideration of the required index. If this parameter appears, the
process continues until flooding has progressed to the point where
no increment to the attained index is being made, or the number
of divisions specified in the /STOP parameter has been processed.
New Features For AXIS Location
AXIS MINGM finds the axis where the GM is minimum.
AXIS MINE:angle [/BOTHdir] finds the axis where the energy is minimum at the
specified heel angle which must be either RA0 or MAXRA. If /BOTH is included,
heel in both directions is checked. Otherwise heel goes in the direction
indicated by the loading or if that is symmetrical, by the ANGLES list. When
complete, the heel direction in which the minimum energy was found is indicated
by the direction in the ANGLES list.
AXIS angles are no longer restricted to 90 degrees. The entire range
(internally converted within plus and minus 180 degrees) is now available.
HEEL MAXRA sets the heel angle to the angle of maximum RA on the current axis.
HEEL RA0 sets the heel angle to the angle at the second intercept on the
current axis.
VARY AXIS:method allows RA and MAXVCG processing to vary the axis angle as it
proceeds. Three methods are available: VARY AXIS:MINASCENT follows the least
ascent in the residual righting moment; VARY AXIS:MINGM increments heel in the
direction of least GM; and VARY AXIS:ZEROTRIM adjusts the axis such that the
trim remains zero. FIX AXIS restores the default behavior.
MAXVCG /AXIS:MINRA finds a new axis where the maximum RA is minimized at
the maximum VCG for each displacement.
HMMT specifications are now associated with the current axis setting.
If the axis is changed to an angle where HMMT has not been specified,
the heeling moment is interpolated using the two sets of HMMT data
on either side of that axis. This does not apply to HMMT WIND, TURN or TANKS.
New Pressure Features For TYPE BUBBLE
LOAD /PRESS:p sets TYPE BUBBLE tanks to the desired pressure p in atmospheres
(note that the primary load parameter is omitted). This adjusts the gas
quantity so that the given pressure creates the tank's liquid load such that
the internal and external pressures are balanced at the reference point.
A new system variable LOAD2 returns the actual load fraction in the current
tank. Note that the existing LOAD variable returns the formal load setting
which may differ from the actual load, and for bubble-type tanks is now always
undefined.
A new system variable BPRESS returns the pressure in a bubble-type tank (in
atmospheres).
TYPE BUBBLE tanks can now have more gas in the bubble. At zero liquid load,
(100% gas) the pressure can now be greater than one atmosphere, in which
case the nominal liquid load will be negative. However since the nominal
load for bubble tanks does not appear in reports, the negative value should
be of no concern.
New Heel Angle For TYPE FROZEN Tanks
The TYPE FROZEN command now allows a parameter to set the heel angle
within the frozen tank: TYPE FROZEN /HEEL:h sets the heel angle to
the specified value. This is particularly useful for tanks where the
frozen contents name has a "!" suffix which locks the heel angle, preventing
it from being changed by other means.
New Deck Edge Marking for CC Cross Curves
CC /MARK:FLood|DEckimm parameter was added to specify whether lowest flooding
critical point (default) or deck edge is marked in the last two table columns.
New TANKS Box Location Selection
TANKS command when used to set a default tanks selection can now
have qualifying slash parameters defining a box which excludes all
tanks named in the given list but lying entirely outside the box.
These parameters are, /ENDs:l1,l2 /INboard:t1 /OUTboard:t2
/BOTtom:v1 /TOP:v2. (For example, "TANKS * /ENDS: 0, 100f".)
If any of these qualifying box dimensions are given and the /INBOARD
parameter is not given, its value is assumed to be zero (port-side
tanks would be excluded). The default values of the other dimensions
are positive and negative infinity.
New Windows Floodable Lengths FL And Tank Soundings TS
ENTER FL executes the new Windows version of the Floodable Lengths program,
which supports 100 shapes, 1000 stations, and 10000 points.
ENTER TS executes the new Windows version of the Tank Soundings Calculator.
New GHS Operating System (GHSOS)
GHSOS.EXE provides basic "GHS Operating System" for manipulating external
programs using dialog box systems run from ".GOS" files.
New MESSAGE SEND Between Multiple Sessions
MESSAGE SEND ON opens a channel for sending commands to concurrent sessions of
GHS32 or GHSOS on the same computer. Subsequent opened sessions communicate
with the first opened session but not with each other. MESSAGE SEND OFF
closes the command channel for a program session. MESSAGE SEND command
sends the given command line to all other sessions if issued from the first
opened session, otherwise the command is sent just to the first session.
DIVISION Enhancements
DIVISION now allows tanks to be assigned to definite inboard and/or upper
layers. An optional suffix is available, which if added to the tank name
designates the layer to which the tank is to be assigned. The suffix has the
form, :In or :Um, where n is a digit ranging from 1 to the number of inboard
spaces in the division, and m is a digit ranging from 1 to the number of upper
spaces in the division. Both the :I and the :U suffix may be used together.
There must not be any spaces between the tank name and the suffix. For example,
DIVISION T123.S:I1:U1.
Note: This feature is usually not required since the automatic assignment of
tanks to layers is normally accurate. However, if it is found, for example,
that an inboard space is being flooded with the wing due to geometry which
changes along the length of the division, the I:n parameter may be used to
override the automatic assignment.
LIMIT Enhancements
LIMIT angle keywords DI and DI0 (Deck/Margin Immersion angle) have been
expanded to allow the angle for any percentage of the immersion angle to be
represented. This is achieved by prefixing a whole percentage to the DI or
DI0 keyword. For example, 80%DI0 is interpreted to mean 80% of the immersion
angle. In addition, a new keyword, FB, standing for Freeboard, has been
introduced which must be prefixed by a percentage. For example, 80%FB is the
angle where 80% of the least upright freeboard is immersed (ignoring margin).
The HF (Half Freeboard) keyword can still be used; it is equivalent to 50%FB.
Only one DI/DI0/FB-type limit angle can exist simultaneously.
LIMIT report shows each angle in the STABILITY CRITERION column with a single
decimal place unless the angle rounds to an integer.
When LIMIT RISE is in effect and there is no other reference to the angle
of MAX RA, GHS now uses the absolute righting arm curve for determining
the angle of the maximum. A note to that effect is added at the RA report.
New LIMIT ANGLE keyword EQUPlus represents 150% of the equilibrium angle. It
may also be prefixed by a percentage between 100% and 200% (e.g. "175%EQUP")
to change the default from 150%.
New form of RASR limit: LIMIT RASR AT ang1 [OR ang2 [OR ang3]] > limval.
This limit applies only at the least of the given angles. At this (least)
angle, the ratio of the absolute righting arm to the sine of the angle should
be greater than the given limit value.
LIMIT numbers from 1 to 99 may be specified, though as before only 20 of them
may be simultaneously defined.
MAXVCG Enhancements
The MAXVCG TITLE command is now effective for setting the max VCG data title
when a specific criterion (LIMITS) is absent. This is useful in the case
where the max VCG data is composed from more than one criterion or when the
criterion was defined in a separate run. Formerly the title provided through
MAXVCG TITLE was only appearing in the Load Editor. Now it also appears in
the plot headers. Note that if a criterion with its own title is in effect
it takes precedence over the MAXVCG title.
MAXVCG now recovers from trim capsizing due to extremely high VCGs resulting
from short ranges of stability.
MAXVCG where the solution VCG was extremely high was sometimes not yielding
a zero margin but rather leaving the VCG lower than it could have been.
MAXVCG print-table header expanded to include information about the heeling
moment and axis-selection mechanism in use.
MAXVCG error "Need closer angles" is now much less likely to occur.
MAXVCG now restores the angles list (SOLVE MAXVCG still leaves it modified
so that RA /LIM can be easily used to verify the SOLVE MAXVCG result).
MAXVCG solving speed was improved for cases where the angle at max RA is
difficult to determine.
REPORT Header And Footer Standardization
REPORT headers and subtitles have been standardized for all regular, plot, and
CG output pages, with company information centered on the first line and vessel
title centered in bold face on the second line.
PRINT footers were sometimes losing the top line of the footer box, overflowing
footer text in case of disproportionately wide footer logos, failing to evenly
space on either side of footer text, and reducing maximum plot length slightly
more than necessary.
PRINT footers with logo but no text appear in a 6.67 inch by 0.67 inch box.
Logo bitmap files this size or larger with a 10 to 1 width to height ratio
(plus or minus 5% to allow for the box thickness) are stretched to fill the box.
PRINT /HEADMARGIN:inches parameter was added to specify the margin above the
header in inches. The default value 0.5 inches is assumed by all GHS report
generating programs, so beware that increasing header margin much beyond 0.5
inches could cause collision of report data with the footer or bottom of the
page. The printer-specific minimum header top margin is used by /HEADMARGIN:0.
SOLVE Precision And Repeatability Enhancements
SOLVE precision and repeatability are greatly improved.
SOLVE /INIT parameter was added to precede solving by resetting heel
and trim to zero along with any history-dependent invisible data normally
used by the program to improve the efficiency of the solving process.
The purpose is to ensure repeatability of results regardless of history.
LOAD EDIT /INITSOLVE parameter was added to initialize heel and trim to zero
along with history-dependent data before any solving controlled by Load Editor.
This does not affect any explicit SOLVE commands in Load Editor macros.
LS /INITSOLVE parameter was added to initialize heel and trim to zero along with
history-dependent data before any solving controlled by Longitudinal Strength.
GHS /GMTRA Parameter Enhancements
The effect of the /GMRA parameter has been changed, as follows.
1. In the GHS command, /GMRA now causes the righting-arm-derived GMt to be
reported regardless of how it compares with the waterplane-derived GMt.
Formerly if the difference was small, a blended value between two was reported.
However if the waterplane-derived value is less than the value reported,
a cautionary note is automatically added which gives the waterplane "standard"
value.
2. In the RA, MAXVCG and SOLVE MAXVCG/MAXWEIGHT commands, the /GMRA parameter
now uses the lesser of the righting-arm-derived GMt and the waterplane-derived
GMt.
The system variable GMTRA now returns the righting-arm-derived value regardless
of the waterplane-derived value.
TEMPLATE Enhancements
TEMPLATE field /Grey[:varname] parameter allows omitting the variable name
to unconditionally disable and grey-out the field.
TEMPLATE dialog boxes no long suspend IDLE macro execution. When a variable
is changed in the background, any corresponding TEMPLATE field is automatically
updated unless it was manually changed by the user since the last time an
execution or exit button was pressed.
TEMPLATE EXPAND field now continues lines ending in "|" to the next line
(other than VARIABLE or SET commands) while remaining on the same dialog row.
Expanding a macro that itself contains an EXPAND field permits generation of
a repetitive series of fields across a repetitive series of rows. The IF
command works during expansion, just like the VARIABLE and SET commands.
TEMPLATE field /Left and /Right parameters were added to left or right justify
button field labels instead of default centering. For CHECK and RADIO button
fields, the /Left parameter puts the label on the left side of the button
instead of the default right side (right-justifying if /Right is also present).
These parameters also work for LEw /BUTTON tool template fields.
TEMPLATE field /Backcolor:n parameter was added to specify the background color
for all text, image, box, button, and input fields, using color number n from
0 to 15 as described for the MESSAGE COLOR command (0=black).
TEMPLATE /Color:fn /Backcolor:bn parameters were added to specify default
foreground and background colors for all text, image, box, check, and radio
fields, using color numbers fn and bn from 0 to 15 as described for the
MESSAGE COLOR command (0=black). The /B:bn color is also used to paint the
overall background of the TEMPLATE dialog box, affecting all fields flat on
the dialog but not raised push buttons, variable fields, or drop-down lists.
These parameters also work for LEw /BUTTON tool TEMPLATE definitions.
TEMPLATE /POS:position string may include the tag "SAME" (e.g. /POS:SAME,
/POS:SAMETOPLEFT) to display subsequent executions of the template at the
same screen position where its dialog box last appeared. This has the same
effect as the now-obsolete EXECUTE /SAMEPOS parameter (which is no longer
documented but maintained for backwards compatibility where it doesn't conflict
with other slash parameter usage, such as TEMPLATE execute button fields).
TEMPLATE field /Left, /Right, and /CENter parameters are now applicable to
static text fields to override the default justification (which is left for
normal text fields, and right for tags appearing left of variable fields).
These parameters are also applicable to variable input fields to override
the default left justification of edit text.
TEMPLATE field /Left, /Right, and /CENter parameters are now applicable to
static image fields to override the default center justification.
Load Editor for Windows (LEw) Enhancements
LEw right-clicking a tank's vessel graph in Tanks mode offers a submenu for
changing the tank load percentage.
LEw right-clicking a "Tank Description" field or vessel graph in Tanks mode
offers a submenu for changing the tank's color (used for description text,
any vessel graph reference point, and Condition Graphics display).
LEw right-clicking a vessel graph in any non-Tanks mode offers a choice to
"Move CG here" for the current item (moving the LCG and VCG if right-clicking
in the Profile view, or moving the LCG and TCG if in the Plan view).
LEw vessel graphs in "True aspect" view mode now display with precisely the
true aspect ratio, leaving an unused grey area as necessary; previously the
true aspect was targeted but then stretched to fill any extra window space.
LOAD EDIT /BUTTON:template assigns keyboard shortcuts for tool column buttons
by ending the label with "|" followed by one letter for a single Alt key
shortcut (e.g. "|X" for Alt-X) or two letters for a double Alt key shortcut
(e.g. "|AB" for Alt-A followed by either Alt-B or B). Right-clicking a tool
column button displays its keyboard shortcut assignments. Keyboard shortcuts
can also be underlined on a displayed text label by putting "_" before each
character that should be underlined (e.g. "_Ballast _Advisory|BA" to mark
Alt-BA shortcut). A double "__" causes single "_" to appear in a text label.
LOAD EDIT /BUTTON:template labels without associated macros appear with dark
grey background only if they are entirely blank, otherwise appearing with
default button background unless the /B:color parameter is used.
LOAD EDIT /LOGOCOLOR:[fc][,bc] now permits specifying 6-digit hexadecimal bc
for background color behind logo text fc and around LEw display areas.
LEw standard tool buttons can all be right-clicked to show their descriptions
and any associated control key combinations.
New System Variables
Operating system environment variables can be retrieved using {%name%}.
BGN system variable was added to return the waterplane-normal distance from
center of buoyancy to center of gravity.
BPRESS system variable was added to return the pressure in atmospheres
for a TYPE BUBBLE tank.
EQUNOW system variable was added to be set to 1 whenever SOLVE is done with
varying heel and trim, and reset to 0 whenever any change is made that might
affect the equilibrium condition. This variable may be set by the user to
override the system setting until another SOLVE is performed.
FLDNUM system variable was added to return the critical point number of the
lowest flooding point. Both FLDNUM and FLDHT include weathertight points only
if EQUNOW=1.
LIMNUM system variable was added to return the limit number corresponding to
the least limit margin in LIMMARG (0 if no limit margin is currently defined).
LOAD2 system variable was added to return the actual load fraction in the
current tank (which may differ from the formal load returned by LOAD variable).
draft value is to be returned by the new DRVALU real system variable.
ROSTABH and MAXRRAH system variables were added to return the range of residual
stability and maximum residual righting arm. Both apply to the range of heel
angles between the present heel and the next negative-sloping occurrence of
zero righting arm in the direction of the present heel.
STRMARG real system variable was added to return the percentage margin of
maximum stress above any /LIMSTRESS:limit from the last LS command.
TGTHT and TGTNUM system variables were added to return height and number of
the lowest TIGHT (weathertight) critical point.
======= Minor New Features =======
CUSTOM (GHSERIAL) now supports $TYPE AN-PRO3 protocol (in "Fixed TX" broadcast
mode) along with $TYPE Sentry IV. The following new configuration parameters
were added for the GHSERIAL.DAT file:
$STARTCHAR value - ASCII value of start of packet character.
$SEPCHARS value,... - ASCII values of allowed field separator characters.
These parameters only need to be configured if they differ from the default
specified the protocol (requires updated GHSERIAL.DLL and permissions).
DAMSTAB /SDI was not going beyond about 30 divisions even when more
than 30 were defined. The limit on the number of divisions has been
increased to 75.
DAMSTAB /SDI now handles penetration across the centerline more consistently.
DAMSTAB /SDI now ignores portions of tanks above the horizontal bulkhead
specified by the DIVISIONS /HBDH parameter when finding their most-outboard
point.
EDIT command now works with long file names containing spaces.
ENTER PM now works under Windows XP x64 and Windows Vista using automatic
DOSBox emulation (requires DOSBox loaded in GHS program subdirectory).
ERASE /NORecycle parameter added to prevent erased files from being recycled.
ERASE (without /NORecycle) is now the only GHS command which recycles files.
ENTER BARGE [paramfile [geofile]] [/WAIT] now runs BARGE.EXE to generate
geofile from paramfile (defaults BARGE.GF1 and BARGE.PAR); optional /WAIT
waits to show hull generation information (requires HM module).
File extension for the default program library file has been changed from
".LIB" to ".LF" (for example, GHS.LIB is now GHS.LF). If GHS.LF is missing
but GHS.LIB exists, then GHS.LIB is copied to GHS.LF, and a message is inserted
at the beginning of GHS.LIB indicating that it has been superseded by GHS.LF.
GHSCOM now supports the END, EXECUTE, EXIT, and MACRO commands.
HMMT REPORT has been improved to represent port-side heeling moments in a
more straightforward manner, and to include all types of heeling moment.
LS no longer restricts the number of weight density points by trapping "Too
many weight density points".
LS report title is abbreviated if necessary to avoid truncation.
MB SOLVE SECONDARY channel,p,s connects using commmand-only mode if either
p or s is zero, or if both are negative. The p and s numbers must be between
0 and 99, but no longer have to be defined as Critical Point numbers for
command-only mode.
MESSAGE PLOTLABEL "labelX", "labelY" no longer uses a general scale when
only two columns are present, instead placing "labelX" and "labelY" alongside
the plot's axes with no legend or arrow markers, ignoring any "%" in labels.
Model Converter supports FIXUP of AutoHydro modified .GF files with the
following problems: illegal characters such as spaces in part and component
names (converted to "_"); more than 12 characters before "." side suffix in
part and component names (shortened with a warning message); "L:" or "W:"
information given as zero (line ignored).
Model Converter importing of HEC file format increased maximum number of
stations from 125 to 1000.
MC /PTOL%:tolerance parameter was added to specify the tolerance (default=1%)
for removing redundant points as a percentage of the sum of the maximum width
and height of the vessel. A point is susceptible to being removed if it is
separated from roughly-collinear adjoining points by less than this tolerance
distance.
PRINT CONFIGURE DEFAULT restores use of the Windows default printer.
PRINT command no longer shows plot info lines in the screen's command area.
PROJECT projdir [(datadir)] command supports quotes around projdir and datadir,
allowing long file names including spaces within projdir and datadir.
Project menu has been redesigned to be more intuitive and useful, including
project browsing and a list of most recently-used projects for quick access.
RA plots show a vertical hair line at the angle of deck immersion (even in
/GRAPH:CLEAN mode).
READ command recognizes "C" or "F" suffix on "OIL@temperature" contents
description; if omitted, the unit setting determines whether Centigrade or
Fahrenheit is assumed.
SCREEN ROWS default minimum number of rows for the command area and Load Editor
spreadsheet has been raised from 2 to 4.
STATUS /PERMFOOT parameter was added to cause the usual "Permeability override"
notices to be omitted and instead appends a note saying "Permeability changes
are in effect".
TC /SOUND now works with loads provided through ullages as well as loads
provided through load fractions. This allows both ullages and soundings
to be in the same TC table.
======= Bug Fixes =======
CONTENTS command was mishandling temperatures in metric mode for alternative
petroleum substances with names larger than 4 characters in metric mode.
DAMSTAB /SDI with very short division lengths was causing the division
sequence to repeat endlessly.
DAMSTAB /SDI /QUICK was not resetting the list of tanks to be flooded between
cases.
DAMSTAB /SDIC /MACRO was storing unnecessary leading spaces in the DAMSTAB_TANKS
variable.
DAMSTAB /SDI now assumes starboard-side damage when a division's tanks are
equally on the port and starboard sides.
DAMSTAB /SDIC /MACRO was not protecting the report against negative range
values from the macro (zero is now substituted).
DISPLAY STATUS plan and profile views were fixed to prevent fill color from
leaking out of narrow or oddly-shaped components, to prevent contents color
from flooding over the waterline into the top part of a curved tank as if it
were full, and to show the correct fore and aft contours of each shape.
DISPLAY STATUS body view was fixed to properly color double components
containing separate port and starboard lobes, and to correctly fill the
waterline for oddly shaped components.
DISPLAY STATUS PROFILE @ angle was trapping "Real number required" if the
angle had a "S" or "P" suffix.
DISPLAY STATUS printout was sometimes trapping "Missing a coordinate".
DISPLAY STATUS plan/profile slice printout was showing labels in random
locations for tanks not intersecting the slice.
DISPLAY STATUS printing with no footer present was not using the full size
of the page (reducing as if a 12 line footer were present); a slightly larger
print region is also used when a footer is present (since 9.84A only).
DISPLAY STATUS /SYNC was not properly updating for vessel angle changes if
the initial waterplane was undefined or flat.
DISPLAY STATUS immediately followed by a NOTE command with a report open was
writing the note text alone on a page without a page header (since 9.38 only).
ENTER TSX, GS, and PMX were hanging if a report file was open (since 9.64 only).
ENTER for certain accessory programs were occasionally trapping "Invalid
location" run-time error (since 9.60B only).
ENTER program runfile converts the "runfile" parameter to short file name
version if necessary for passing to Part Maker.
ENTER PM was setting the ERROR system variable to zero if the geometry file
was changed (since 9.68B only).
ENTER GS was improved to work starting in long file name directories, have
a uniform border color, and have slight margin at the top of its graphs.
Error reporting no longer truncates long command lines.
EXECUTE template|commandline was skipping commandline if a button was pressed
in the template dialog which executed a macro or subtemplate.
Fancy report printing was sometimes misformatting the second line of page
headers when the title is extremely long.
Fancy reports were sometimes treating a pair of adjoining sentences separated
on a line by two spaces as a pair of separately-aligned fields in a table.
FSM values of tanks in spilling mode were being reported for the surface
at the nominal load setting rather than for the surface at the spill point
(since 8.76C only).
GHS command report with non-zero axis was sometimes giving a spurious warning
message regarding standard GMt.
GMT and GMTRA system variables no longer affect the current waterplane.
Calculation of GMT derived from the righting arm curve was throwing off
aberrant values in rare cases (since 9.62C only).
HELP and VIEW commands were sometimes inserting spurious blank lines into
their displays.
HMMT REPORT was sometimes showing small spurious OTHER amounts when HMMT /GUST
factors are used or due to tolerances in the caching mechanism. The cache is
now bypassed by HMMT REPORT.
IF EOL and multi-variable READ x,... were not always behaving properly on the
final line of a READ (DATA) file.
Internal ellipses ("...") copied into run files via Notepad are now readable.
LEw was not always restoring the original GHS window dimensions on exit
when using a /BUTTON template so large that the LEw window filled the screen.
LEw macro errors were waiting for "Press to continue" before displaying the
error message (since 9.72A only).
LEw right-clicking "Move CG here" was sometimes failing to refresh the TCG
or VCG on the current weight row.
LEw "Ground Points" mode was sometimes failing to accept negative values and
triggering wild solving when appending new ground points.
LEw using tool buttons was occasionally trapping "Invalid location" run-time
error after returning from execution of an external program.
LEw with tool column buttons was sometimes trapping "Invalid index" run-time
error when restarting itself using another LOAD EDIT /BUTTON command.
LEw was not restoring display of waterplane-derived GMt when Ctrl-R was pressed
twice (in and out of RA-derived GMt mode). LEw now shows "Maximum VCG" as
"unknown" if not within defined data range.
LEw "Solve" buttons were ineffective to force solving after calling a macro
which changed only heeling or trimming moments.
LIMIT FLOODHT AT EQU was not always reporting the correct flooding point
height at equilibrium.
LIMIT angle PRE was being treated as a lower limit rather than an upper limit
which made it unusable in the MAXVCG process.
LOAD EDIT /SCREEN:MAX|MIN was not properly restoring the previous window state
on Load Editor exit if an intervening macro execution had restarted LEw using
another LOAD EDIT /SCREEN:MAX:MIN command.
Load Editor was sometimes trapping "GAMMA FAULT TYPE 1" error when flooding a
tank set up with flood override permeability using the PERM FLOOD command.
MAXVCG /AXIS was not showing the axis angles in /COMPOSITE mode.
MAXVCG with EQU0 in the limits was, in some cases, stopping prematurely
and reporting the error "Heel out of range".
MAXVCG process was not reversing the heeling moment when port-side flooding
and starboard-directed heeling moments were given simultaneously.
MAXVCG interpolations were sometimes overshooting seriously in cases of
quasi-discontinuities in the given MAXVCG data.
MAXVCG /TRIM:...n/ was failing to divide n by the current LWL for the last
listed trim value, instead treating n as degrees (since 9.96E only).
MAXVCG tables were misformatted if more than 9 limits are defined; now any
limits after the first 9 do not appear in MAXVCG tables.
MAXVCG was not running as efficiently with intact tanks loaded (which are
ignored by MAXVCG processing in any case).
MAXVCG processing was not completing in rare cases when a relative LIMIT angle
was exceeding 180 degrees.
MB SOLVE SEND (n) command was not restricting command transmission to the
session connected to primary critical point n.
MC was trapping "Ran out of memory" when importing HEC .HUL files
containing Appended Volumes with nominal zero height; now these Appended
Volumes are treated as cubes.
MC was trapping "Invalid location" run-time error when converting IDF files
that had duplicate stations at the first station location.
MC error reporting for defective IDF files was overwriting the station number
which triggered the error.
MC was not allowing lowercase $-prefixed tags while importing IDF files.
MC file [(component)] FIXUP uses * not HULL\HULL.C as the default component.
MC /TANKORDER:OrderFile was ineffective for lowercase tank names listed in
the OrderFile.
MC was sometimes trapping "System Fault 3 in module GAdd" when converting
files with stations containing more than 100 points.
MC was sometimes neglecting to clean out excess points from a station.
MESSAGE PLOT report printing was trapping "Unknown keyword" if any plot data
values were empty. Now any missing plot data is treated as undefined and any
excess plot data is truncated.
Mouse scroll wheeling was sometimes causing a program crash on some systems.
NOTE (n) advances the report page if n is zero or the page is at least half
full and there are fewer than n lines remaining on the current page, otherwise
outputting a blank line. This was previously an undocumented feature, but was
being triggered even when the initial "(" was omitted. Note that "\ (n)" can
be used to actually output " (n)".
Possible run-time errors for mouse wheels and printer configuration were fixed.
PAGE 0 mode was being turned off by external programs, so page numbers resumed
upon their return. Condition Graphics was showing pages even in PAGE 0 mode.
Doing PAGE 0 immediately after a Condition Graphics returned was sending an
extra line before the page header.
PRINT CONFIGURE attempts to address configuration problems with certain
printers.
RA /LIM was failing to register downflooding angle in some cases
when it occured at heel angles greater than 90 degrees.
RA /LIM /NOTAB table was misformatted in fancy reports.
READ command was reading any tanks with "OIL@temperature" contents description
incorrectly, so an error would be trapped after a SAVE and restore.
READ file was creating an empty file and trapping "Corrupt geometry file"
if a file with a long path specification doesn't exist.
REPORT opening was not turning off any MESSAGE REPFONT.
ROLL report was showing the roll period as a very large number which overflowed
the field when GM is negative. Now the field is left blank when the GM is zero
or negative.
SCREEN ROWS min max was ineffective when min and max values were equal.
SET LEFT, RIGHT, and SLICE operators were failing for strings longer than
255 characters.
SOLVE MAXWEIGHT /FSM was ignoring the /FSM parameter.
SOLVE limit on number of waterplane endings increased to avoid "Too many
waterplane endings" error.
STATUS CRTPT:BRIEF now works properly. Formerly it was not reporting any
critical points: it now reports the lowest.
TEMPLATE EXPAND was failing for VARIABLE command followed by parentheses
without an intervening space.
TEMPLATE EXIT macro field, used by itself without a label, was disappearing
unless used as the last field of a template, in which case it assigns a macro
for the default "OK" button (since 9.40B only).
WRITE command was not reliably saving TYPE CALIBRATED information, but for
uncalibrated tanks was sometimes writing spurious TYPE CA lines which have
no effect in the usual case where property tables are absent from the geometry
file (since 9.98H only).
WRITE (SAVE) avoids a conflict of "OIL @ temp" uses by writing the contents
table before the tank parameter settings.
GHS32 clicking above the command line in a blank part of the display was
temporarily changing the color of command line input from cyan to the message
color (since 9.96B only).
GHS32 was sometimes hanging when the program was closed while waiting for
"Press to continue" following an error.
GHS32 was always starting in a normal window even when run from a shortcut that
specified a maximized window.
