Define Globals from C app?

Hello,

I'd like to have my system library code define globals like you can do in the *.pmh files, but from C code.

The reason is that I have several system variables I want mapped to fixed P vars, but still use the symbolic string based reads through gpascii from my HMI program. Otherwise I have to have my HMI programs cross reference the P vars with duplicated definitions across different project environments (which is what I do now, but gets into version nightmares if I remap the system vars).

The reason I can't do it in the project *.pmh files is that this is my system library that gets included across multiple projects.

Is this possible/practical to do?

Thanks,

KEJR
