Need to walk a whole VSAM file under CICS. Doing READNEXT in a loop. How do people detect end? Is there an END-OF-FILE flag or do I watch RESP?

STARTBR, then READNEXT until RESP = ENDFILE (or DFHRESP(ENDFILE)), then ENDBR.
Do not guess from key values. Check RESP every time.
And put RESP2 on the commands when you get INVREQ. RESP 16 alone is not enough detail.
