Set a macro value using script

[kinook]

From a Run Script action, use something like this:

Application.Macros(vbldMacroTemporary).Add "MACRO_NAME", "macro value"

If the VBScript code is external to VBP (i.e., a .vbs file), you would need to instantiate the object model and store in a project (loading the appropriate .bld file first) or global macro.
