VSI OpenVMS Forum

Can I set a #define in a VMS IDE project? I am currently using __ALPHA to mark code specific to VMS (and _WIN64 to mark code specific to Windows).

However, if in future I'll compile for Itanium and x64 as well (and to avoid confusion with Windows targets) I'd prefer an architecture-agnostic VMS define.

You can use __VMS, see
$ help cc Language_topics Predefined_Macros System_Identification_Macros

No, but You can do it via MMS.

If I do via MMS, VS Code won't know about it though.
