Not sure what exactly you need, ... but with embedded SQL you should be able
to check if the member and/or the program are available:

1. Check whether the member exists
Clear isFound;
Exec SQL
Select 1 into :IsFound
from syspartitionstat
Where system_Table_Schema = :HostSrcLib
and System_Table_Name = :HostSrcFile
and System_Table_Member = :HostSrcMbr;

2. Check whether the Program/Service Program exists
Clear isFound;
Exec SQL
Select 1 into :IsFound
from Table(Qsys2.Object_Statistics(Object_Schema => :HostObjLib,
Objtypelist => '*PGM,
*SRVPGM',
Object_Name => :HostPGM)) ;


Mit freundlichen Grüßen / Best regards

Subject: Checking for existence of members and programs?

I've been asked, in an RPG program that generates other RPG programs (I find
myself doing that a lot, the past few years), to generate names for the
programs being generated.

I'm already (for manually chosen and entered names) checking for member name
collisions simply by watching for errors returned by a call to the ADDPFM
command, and I'm using a call to the CHKOBJ command to determine whether the
program already exists, but I don't even want to think about that for
generated names.

For argument's sake, let's assume the generated names are of the form
AABCCxxxxx, where AABCC is determined by what the generated program does,
and xxxxx is a 5-digit number. And that users might not bother to override
the generated name for programs they want to keep for future use, and may or
may not bother to delete the programs (or
source-members) generated for one-time use.

Any suggestions?
