To prevent situations in which SAS might stop responding, SAS 9.2 was changed so that it uses sockets (BPX1SOC). Consequently, some commands that worked in releases of SAS before SAS 9.2 might not work. This includes TSO commands. Here is an example. In SAS 9.2 and later, this code returns messages to the SAS log:

  FILENAME TEST PIPE '/bin/tso listcat';

  DATA _NULL_;
   INFILE TEST;
    INPUT;
   PUT _INFILE_;
  RUN;

The SAS log shows the following instead of output from the listcat command:

FOMF0134I TSO Environment service failed: rc=36 rsn=300
 listcat
 FOMF0134I TSOLNK failed: rc=20 rsn=24 code=0

You might also see the following warning in the SAS log:

Features that IBM added to z/OS version 1.12 and later should prevent the situations in which SAS stops responding.
