I have a VSAM ESDS that gets dynamically allocated with status of MOD. The
dataset is normally opened for read only. At one point in the logic, new
records need to be added to the end of the dataset. When this occurs, I close
the dataset, re-gen the ACB, and try to re-open it. I keep getting a return
code of 8 from the OPEN. I've specified MAREA on the ACB, but nothing is in
this area after the OPEN. The ACBERFLG field is 0's as well, but the return
code from OPEN is 8. The macrf from the first OPEN for read only is
MACRF=(ADR,NDF,DIR,SEQ,IN,NSR,NUB). The macrf for the update is
(ADR,NDF,DIR,SEQ,OUT,NSR,NUB). Obviously I'm doing something wrong, and would
appreciate any help. How do I get VSAM to indicate to me what it doesn't like
about wha I'm trying to do?
