How do I programmatically set ‘parameter macros’ for a 'Subroutine Call'?

[Dave_Novak]

I am programmatically generating build steps using VBScript and the VBP object model. Although the object model is typically easy to program, I am having some problems setting up ‘parameter macros’ for a 'Subroutine Call'.

Could you possibly provide an example of how this is done?

Thanks.
