Answer

There is an option in CPYF command which says " Error Allowed", making that as *NOMAX will trigger IGNORE option instead of CANCEL in CPYF processing; whenever there is duplicate record encountered.

Go to WRKACTJOB and hit F14 to include all the disconnected jobs, if that job is still active it will be visible there.

Question { 3756 }

In case if I want to know whether a record exists in a file, which one do you prefer CHAIN or a SETLL and why ?

Answer

If you just want to know whether the record exists or not, SETLL is best as it just points to the record and doesn't store the data in to fields ( time saving ) where as CHAIN will read and stores the data in to fields ( time consuming ).
