Listing of GISDK Functions
GISDK function names are not case sensitive. The listing for each GISDK function contains the following sections:
| Section | Contents |
|---|---|
| Summary | A concise summary of the GISDK function |
| Changes | A description of how the function has changed in this version |
| Syntax | The syntax for using the GISDK function and a description of all arguments |
| Return Value | The type and contents of any values returned by the GISDK function |
| Notes | Information you need to make use of the GISDK function effectively |
| Example | Sample Caliper Script code that makes use of the GISDK function |
| Error Codes | A listing of errors that the GISDK function may signal |
| See Also | Cross-references to related GISDK functions that may be of interest |
Note that sections are omitted if they are not relevant. For example, the Return Value section is omitted for those GISDK functions that do not return a value.
Also note that the Changes sections only show more recent changes. Earlier changes have been removed, and most changes (such as adding a new function or adding an option to an existing function) will not affect compiling or running functions. Please contact Tech Support if you encounter problems with old code that is not compiling or running properly under the latest version.
Most examples can be copied and pasted into the Immediate Execution dialog box, which you display by clicking 
on the GISDK toolbar. For more information, see Compiling and Testing with the GISDK Toolbar. Some of these examples have comments about what you need to do before running the example. Other examples are just illustrative, using fictitious file names, such as C:\MYFIRST.WRKZ.
