PH31470: USING A MSGEXIT WHEN THERE IS NO SYSMDECK DD MAY CAUSE THE COMPILE JOB TO LOOP

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Using a MSGEXIT when there is no SYSMDECK DD may cause the
  compile job to loop.
  Compile job issues:
  IEC130I SYSMDECK DD STATEMENT MISSING
  IGYSI5013-U  An error occurred while attempting to open file
  "SYSMDECK".
  

Local fix

• 1- Cancel compile job
  2- Add SYSMDECK DD for successful job completion
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the Enterprise COBOL V6.3       *
  *                 compiler running a compile from JCL that is  *
  *                 missing the required SYSMDECK DD statement   *
  *                 and also specifies the MSGEXIT compiler      *
  *                 option.                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Infinite loop in abnormal termination   *
  *                      logic: when a batch compile is          *
  *                      submitted and the JCL is missing the    *
  *                      required SYSMDECK DD statement but it   *
  *                      also specifies the MSGEXIT compiler     *
  *                      option, it causes the compiler to fall  *
  *                      into a looping situation.               *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  Even though the compiler does flag the missing SYSMDECK DD
  statement with an appropriate error message(s), it occurs after
  the user MSGEXIT has already been located and loaded. This
  prevented the abnormal termination logic from working
  correctly.
  

Problem conclusion

• The compiler has been updated so it detects the missing SYSMDECK
  DD statement earlier, issues appropriate error msg(s) and
  immediately terminates. This prevents the infinite loop in the
  abnormal termination logic which was caused by attempting to
  unload the MSGEXIT and close compiler work files which had not
  yet been opened.
