Ok, I was missing something simple. Thanks for the clarification.
But....
Nope, bitches like a wife in overdrive at <UINT32>. I don't see this in the
Learning Reference of vartypes I can use in a Soft Declare. I tried to
substitute with a simple Integer. Then I got an undefined return type error in
the soft declare. Is there a vartype I can substitute to make this work?
Bloodied but not discouraged...
