RE: Dynamic call with procedure pointers

[rob@xxxxxxxxx]

Wouldn't this work:
http://localhost:49213/plugins/com.ibm.etools.iseries.ilerpg.doc/html/evfrilsh365.htm#HDRDEXTPGM

     D MyProc          PR                  ExtPgm(MyPgm)

     C/FREE
       MyPgm='GROOVING';
       MyProc();

That will work if I wasn't using /Free.  Making a dynamic call in /Free
appears as if it is not possible with CALLP (CALL and CALLB aren't 
available
in /Free).

If I do something like the following:

pgm = 'RECSHPNOT';
CALLP pgm(inputFile: outputFile);

it thinks I am trying to reference 'pgm' as an array rather than use the
value in 'pgm'.

Anybody think of a way I can do this in /Free?  It looks like I will have 
to
go back to fixed for this particular situation. . .

I may be confused, but if you are trying to call a *PGM object, why not 
use
the CALL operation code with a variable name.  Something like

select
when something
eval pgmname = 'RECSHPNOT'
endsl

call pgmname

This is as dynamic as it gets.

If you are trying to run a procedure within RECSHPNOT (on the fly), then
perhaps you need to recompile RECSHPNOT so that it is a *SRVPGM object?
