GHS Beta-Version Update History from Version 12.50 to 13.00


GHS Beta-Version Update History since Version 13.00

Version 13.00A

GROUND command increased maximum number of ground points to 400.  Note that
excessive ground points may slow down program execution without necessarily
producing any more useful information (requires updated CG.EXE).

WPLEN system variable was returning the length of the underwater block instead
of the waterplane length for bulbous-bow vessels.

COMP /FORM was sometimes slightly undervaluing the waterplane length for
bulbous-bow vessels.

GHS command nondisplay output was not writing displacement volume correctly
using metric units.


Version 13.00B

SET operations now work correctly even when the internal command line length
exceeds the documented 10,000 maximum due to very large variable replacement.

CLEAR was not always clearing any watermark vessel graphic (since 12.98A only).


Version 13.00C

ENTER PM statement KLOCUS was not forcing linear interpolation for added
stations around knuckles in certain cases (requires updated PM.EXE).

VARIABLE and EXECUTE now work correctly with very long commands.

SET QITEM operator was removed due to redundancy with ITEM operator, which
also removes any quotes surrounding items (since 12.90B only).

TEMPLATE entry error messages were sometimes overflowing for excessive data.


Version 13.00D

ENTER PM statement LOCUS was incorrectly closing centerline components off
the centerline when the last given point is off the centerline (since 12.92
only; requires updated PM.EXE).


Version 13.00E

DIR /MACro:name [parameters] was added to skip listing to the screen, instead
listing to the named macro by executing it repeatedly, each time passing as its
final parameter the next matching file or subdirectory name in the specified
directory.  Up to 8 initial parameters can be specified after the macro name.

ENTER PM statement FIT was occasionally leaving unbound stations (requires
updated PM.EXE).


Version 13.02

ENTER PM, MC, and SE now preserve any miscellaneous-information lines included
before the first shape in the Geometry File (requires updated PM.EXE, MC.EXE,
and SE.EXE).

DISPLAY STATUS now supports wave effects for flooded tanks in all views, not
just body view.  Spurious wave effects are no longer shown for damaged tanks
in body view (requires updated CG.EXE).

WIND REPORT plot was not output correctly in DISK files with ".DAT" extension.


Version 13.02A

ENTER PM fitting and station interpolation were improved, especially at large
longitudinal locations where bad results occurred in rare cases (requires
updated PM.EXE).


Version 13.02B

CRANE module reduced the minimum permissable jib/main boom ratio from 0.5
to 0.25 to qualify for automatic knuckle angle adjustments.

LIMIT value out of range errors now show minimum or maximum allowed value.

ENTER PM station interpolation was further improved (requires updated PM.EXE).


Version 13.02C

TLCG, TTCG, and TVCG system variables now return the combined center of gravity
of all selected tanks, instead of undefined when more than one tank is selected.

DISPLAY, DISPLAY STATUS, and SE were showing spurious noise on horizontal lines
in rare cases (requires updated SE.EXE and CG.EXE).


Version 13.02D

DRAFT command was setting weight versus buoyancy as if no intact tanks were
present (corrected by SOLVE and any other STATUS-changing commands).


Version 13.02E

UNIT Feet and Ft are allowed for UNIT F, and UNIT Meters is allowed for UNIT M.


Version 13.04

CRANE module improved support for multiple cranes by showing any current crane
number from the BOOMNUM variable in the title of the Crane Input and Data boxes.
Also, LEw now switches the Crane Input box between "Jib Angle" and "Knuckle
Angle" when the BOOMJIB variable is changed.

DEPTH command now shows correct delta weight versus buoyancy in the header
as well as any subsequent STATUS report.

PRINT filename.PF (or opening filename.PF from the operating system) no longer
traps an error if the given filename contains a period before ".PF".


Version 13.04A

Repeated SOLVE commands under identical conditions will tend to progressively
reduce the tolerance and increase the precision of the weight versus buoyancy
solution (as was already happening for righting arm heel & trim solutions).

SE was trapping "Coordinates bad" when entered in UNITS FIS mode (since 11.12B
only; requires updated SE.EXE).


Version 13.04B

RA /SIZE plots now always extend to the full specified angle range even when
the /STOP parameter is present.
