B LOOP
NOTACCEP ... Request wasn't accepted.
ERROR ... Display feedback field (FIELDS=FDBK) of x
each request list to determine which x
one had an error.
AREA1 DS CL50 A single GET request causes VSAM to put x
a record in AREA1, AREA2, and AREA3.
AREA2 DS CL50
AREA3 DS CL50
After the CHECK, register 15 is set to indicate the status of the request. A code of 0 indicates that no error was associated with any of the request parameter lists. Any other code indicates that an error occurred for one of the request parameter lists. You should issue a SHOWCB macro for each request parameter list in the chain to find out which one had an error. VSAM does not process any of the request parameter lists beyond the one with an error.
