Dear friends...
I have two questions, if you know the answer please reply

1.I have a KSDS file which is processing in my cobol program. Assume that the KSDS file contains 1000 records and currently 500 th record is processing. Now instead of processing the further records, i want to process the first record. How can i go to first record with out using the START Command and without closing the file .

2. How buffer are allocated to VSAM files?

1) If you defined the file access as DIRECT or DYNAMIC save the key of the 1st rec then do a direct read whenever the urge hits you.

If you defined the file access as SEQUENTAIL you're screwed.

2) Can you be more specific? Use examples, etc.?

Kandasamy,
Through the JCL DCB parms like BUFNO, BUFIN, BUFOUT for VSAM files.

Shouldn't this topic be in VSAM & DFSORT as originally posted. Is there any particular reason behind the move. Just curious...
