Re: cl program to call two rpgle programs

Hi,

1) But how would it be identified in the CL via a MONMSG?
It would be nice if some example someone could provide for this case.

2) How does Program A intentionally set that parameter value which CL can
use to identify whether it 'OK' to go on and Call Program B or not ?

Thanks much...

The main ways that your CL can know that the call to ProgramA ended in
error are:

1. An unhandled exception occurred in ProgramA - this would be identified
in the CL via a MONMSG as Jon told you above.
2. ProgramA intentionally sets a parameter value which the CL can use to
identify whether it is OK to go on and call ProgramB or not.

These are not mutually exclusive, they are handling different types of
error conditions.

Hi,

But problem is that program 1 has many if /else conditions and what will
happen if my program 1 falls under some error condition which it has
multiple error conditions in it.
So how will i be able to cope with this situation because program 2 from
this CL should only be called once program1 is completed normally here
normally means it should be able to do all those desired activities for
which it has been designed.
Also even in some positive scenarios all goes good and program 1 gets
completed successfully then how will my CL program come to know that it\s
time to execute program 2 now.


Thanks much...

I'd argue that too tightly couples the two programs.

Proper checks can be made in the CL to see that program 1 completes
as
desired before calling program 2.

I'd consider calling programB from programA, so that programB only
runs
if
and how programA wants it to run.

Hi,

I am trying to write a CL prgram which should call two independent
RPGLE
Programs,
I am trying this to club these 2 different RPGLE programs so that
they
should run in a same job but problem is that these 2 RPGLE programs
are
very complex and have different if else conditions so how can I club
them
together also once first RPGLE program gets completed then only
secondone
should be invoked.


Thanks
