Re: CHKOBJ in RPG IV programme

You could call QCMDEXC to execute the CHKOBJ command. If you prototype
QCMDEXE and call with CALLP(E), you can use to %ERROR to determine if the if
the command ran OK.

If CHKOBJ does not find an object it returns an error message CPF9801. Other
error messages are returned if you are not authorised to an object. Check
%ERROR, then find the error message details in the Program Status Data
Structure. This should provide you with all the information you need.

In short - if object exists, no error message, %ERROR ='0'.  If object does
not exist, error message details in PgmDS and %ERROR = '1'.
