Here are some facts about GHS vs. GHSX:
1. The computer codes that form GHS are of three types: GHS modules, GHSX modules, and "neutral" modules. ("Modules" here refers to computer-code modules, not the programs or features licensed as optional modules.) 2. Code Modules are linked in various ways to make the programs (.EXE files) collectively known as GHS. 3. GHSX-code modules are used to build Part Maker (PM/PMX), Section Editor (SE/DISPLAY), Condition Graphics (CG), Tank Soundings Extended (TSX), Grain Shift (GS), and Model Converter (MC). 4. GHS-code modules are used to build everything else. This includes the GHS main programs (GHS, GLM, BHS) and their native optional modules such as Load Editor (LE), Longitudinal Strength (LS), Floodable Lengths (FL), Tank Soundings (TS), Advanced Features (AF), and Multi-Body (MB). 5. Neutral modules are written in such a way that they can be linked with either GHS or GHSX code. Sea Keeping (SK) uses neutral modules. Also, templates are implemented in a neutral module. This allows the TEMPLATE command to appear both in GHS and in GHSX-based products such as PM/PMX, TSX, and GS. 6. Additionally there are the two "command languages" of GHS and GHSX. Most wizards are written in the GHS command language, but those that deal with geometry typically depend on the GHSX command language. 7. Some products, notably Crane and Sensor Interface (SI), are implemented in the GHS command language. Even individual commands can be coded that way (the Advanced-Features STABILITY command is an example). TSX and GS have user interfaces written in the GHSX command language. Note: All modules and wizards are accessed through the GHS main program. Since there is no separate product on the price list called GHSX, you are free to explore what the GHSX command language has to offer. Examples are the library files that come with TSX and GS. These have long been available and open for users to examine and even modify or extend if desired. Other examples of GHSX command language appeared in COW #16 and COW #38. |
