Hi abc421,
Another option in addition to UserCommands would be to use ScriptInclude(path). If you execute a ScriptInclude(path) command at the beginning of your VBScript, then all the functions and Subs in the VBscript located at "path" are now available to you-- including passing parameters and receiving return values from functions. If you are calling a VBscript that uses only VBScript variables, then this is the preferred method.
If instead you are calling a VBScript that uses global DIAdem variables declared in a VAS file (their variable names all end with the "_" character), then those parameters are already available at the subroutine called with ScriptStart(path, routine).
