Re[2]: dynamic program CALLS

[Srinivas.Rao@xxxxxxxxxx (by way of David Gibbs <david@xxxxxxxxxxxx>)]

     In addition to the following reply, it also depends whether you are
     writing ILE program or embedded SQL program. Because in these
     scenarios it varies how you setup your activation groups and
     compilation options.

>>"If PGM_A contains a dynamic call: 'CALL PGM_B' and that line of code is
executed 1,000 times, does the EXACT SAME PROCESS occur 1,000 times? "<<

The answer (as always) is "it depends".  Assuming that PGM_B is an RPG
program,
then as long as it doesn't set on LR before returning, then second and
subsequent calls will be faster as the caller already has a resolved pointer
for the target program.  If LR was set on (or a RCLRSC was done before the
second call) then the whole process has to be repeated.

Was there a particular reason for asking this?
