Problem Note 20583: Concatenation of 257 physical sequential data sets fails when you run SAS® software on z/OS
An enhancement of Release 6.08 of the SAS® System intended to support
concatenation of more than 256 physical sequential data sets to the same
ddname. However, a system abnormal ending will occur if you define
(n*256)+1 data sets (n represents a multiplier of 1,2,3, and so on).
SAS® 8.2 reports this failure in the job log as an S0C4-11 in SASVXSAM
with the SASHOST entry, and the SASXA1 or SASXAL entries (depending on
which SAS bundled entry is used). The SAS log will contain the following
error regarding the step that refers to the concatenated data set:
ERROR: System abend 978 occurred outside of the SAS environment.
In SAS® 9 the JOB step will complete with a return code equal to 8
(RC=8). The SAS log will contain the following error regarding the step
that refers to the concatenated data set:
ERROR: RDJFCB failed for file ZUSUCH, rc = 4.
