RE: Subroutines vs Subprocedures was RE: Indicators

[CWilt@xxxxxxxxxxxx]

Glad to be of help.

I'd agree that it is nice but not particularly perfect.  In fact, it often
bits me in the a** and I have to relearn this particular lesson.  I think
I'm finally to the point where the first thing I look for, when the SQL
pre-compiler says my host variable is unusable, is a non-unique name.

Actually, I should point out (for the archives if nothing else) that the
globally unique requirement is there regardless of rather you are using
global or local variables  in the embedded SQL.  The pre-compiler only has a
global namespace into which it throws all global and local variable names
defined in the RPG program.  Nor has this been corrected in v5r3.


As to your last question...yep been there done that!  ;-)
