That's interesting.  I'm pretty sure CEETSTA does exactly the same thing 
as if %ADDR(PARM)=*NULL.   (Not all languages have the ability to check 
the address of a parameter, indeed RPG didn't have this capability at 
first -- and CL only got it recently.  So CEETSTA is necessary.)

So I guess I'm wondering what's going on here... How the heck does 
CEETSTA solve the problem?  It does the same thing!

You're correct that %PARMS won't work with SQL.  %PARMS is part of that 
operational descriptor I mentined earlier -- and SQL doesn't supply a 
descriptor (not even a minimal one) so there's no parameter count.  But 
that shouldn't have any impact on whether %ADDR(PARM) does or doesn't 
work.  And since CEETSTA is supposed to be identical to %ADDR(PARM) I'm 
a bit confused at your message.
