RE: Dynamic call with procedure pointers

["Bill Hopkins" <BHopkins@xxxxxxxxxxxxxxxxxxx>]

Must be Notes. I already new it was wrapped. 
I just searched and found when I got the message at the Support Center. 
I had this happen before with links posted on list.
Did not know if my side or link.

Thanks 
Bill Hopkins

Wow!  IBM can move links faster than I can post them!  :-)

The url's wrapped.  Try pasting the entire URL into your address bar, that
should fix it.

Thanks Barbara!  That looks like it is exactly what I need.  Here are the
Reference pages for the archives :

http://publib.boulder.ibm.com/iseries/v5r1/ic2924/index.htm?info/apis/qleact
bp.htm (QleActBndPgm)
http://publib.boulder.ibm.com/iseries/v5r1/ic2924/index.htm?info/apis/qleget
exp.htm (QleGetExp)

I will see if I can wrap these with some service programs and get them 
back
to the group for anyone else that needs them.

Aaron, the prototype is necessary to define the parameters and possible
return value.  You can code a procedure pointer in the EXTPROC keyword,
and set the procedure pointer at runtime.

It sounds like you probably know at compile time the possible names you
might want, so you can set the procedure pointer with %PADDR. If not,
there's a way to get a procedure pointer given a service program and
procedure name - search for QleActBndPgm and QleGetExp.
