Isn't this available from the catalog? You might be able to get what you want using the SHOWCAT macro.

Wiegand" <[EMAIL PROTECTED]> Sent by: IBM Mainframe Discussion List <[email protected]> 02/08/2006 03:59 PM Please respond to IBM Mainframe Discussion List <[email protected]> To [email protected] cc Subject READPREV in batch In CICS you can do a STARTBR on a VSAM KSDS or ESDS file and then issue a READPREV to get the previous record from the key you started at. However, this function is not available to COBOL or IBM Assembler in batch. We have an issue where we need to know what the last RBA is in an ESDS file. It would be nice if we could do a STARTBR with a key of high-values and then do a READPREV. Has only via the mother of invention, found a way to do this that is fast? I know we could do a startbr at the begging or somewhere in the middle, do READNEXT saving off the keys until we hit EOF at which point the saved key would be the highest RBA. But we have a huge file and this way would take too much time. Thanks in advance for any suggestions.
