Question

I used to look at the source for %G for this, but lately Intersystems has stopped distributing the .INT code. I guess in theory I could use an eXecute statement in a loop to check $D on every legal global name but that’s silly and unreasonably slow.

So what is currently the right way to do it?

Answer 1

use special global variable ^$GLOBAL

for example:

s global=""
f { 
s global=$o(^$G(global))
  q:global=""
  zw global
}
