Operators

In addition to WEAP's built-in library of functions, you can also write your own functions in standard scripting languages, such as VBScript and JavaScript.  These functions can be accessed from your expressions using the Call function.  The script editor lets you edit the default VBScript file (functions.txt), which is stored in the current area folder.  Thus, you can have different functions specified in different areas.  See Scripting for more information.
