Can I use HEADER1/TRAILER1 parameters with output file VSAM ? and how can I use it?
No, you cannot use HEADER1 or TRAILER1 with a VSAM output file. You cannot use any of the "report" parameters with a VSAM output file. If you try it, you should get the following error message:
ICE224A 0 SORTOUT CANNOT BE USED FOR A REPORT - RECFM WITHOUT 'A' SPECIFIED, OR VSAM DATA SET
Since you didn't provide any information, I can't tell you why you got a S0C4, but I suspect it's some kind of user error. At any rate, you can't do what you want directly. You could use HEADER1 and TRAILER1 to create a non-VSAM file and then copy that non-VSAM file to a VSAM output file.
