Re: dynamic program CALLS

[Jon Paris <paris@xxxxxxxxxx>]

>>"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?
