No, it isn't on the global-shared site.
What I meant was the site would show you Progress Examples of API calls (I didn't know how familiar you were with API stuff).
You could then convert the VB call (plenty of examples on the Net) to Progress.
However, I've just found an example in the progress source files:
Look at src/adecomm/_winsys.p.
That has a call to GlobalMemoryStatus.
