Hello Robert,
PASSPORT Macro engine for .zmc files is written on top of VBScript engine, so it is a superset of VBScript language. Could you please detail which commands in VBScript are not supported in PASSPORT? In addition, Rocket TE Desktop, our main terminal emulation product, supports to edit or run .zmc scripts directly, without PASSPORT installed. Moreover, RTE Desktop's script host can run any other script languages, including Python, that support Windows Script Host interfaces.
Thanks
