PM78072: ABEND S0C4 CSLSXPR0 TRYING TO ISSUE BPE0032I AFTER F <SCITASK>,SHUTDOWN

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer issues F <scitask>,SHUTDOWN.
  Flow:
  BPEMOD00->BPECMD00->BPECMD10->BPEPRNT0+BPEWPRT0->CSLSXPR0
  We are trying to issue BPE0032I message; CSLSXPR0 assumes that
  any message that does not start with 'CSL' and is in fact a
  multi-line WTO where the first 4 bytes of the message text
  point to the actual first text line. BPE0032I is not multi-line
  and we end up trying to use c'BPE0' as an address pointer and
  S0C4. It seems CSLSXPR0 should also check for 'BPE' in the
  single line test.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IMS v11 SCI who have installed  *
  *                 the optional CSL Unsolicited Message User    *
  *                 Table, CSLZUMTU.                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: ABEND0C4 in CSLSXPR0 when SCI prints a  *
  *                      message with BPE prefix                 *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  CSLSXPR0 is the System BPEWPRNT exit for SCI, and is driven
  whenever SCI uses BPEWPRNT to send a console message.  At label
  XPR01100, it determines whether the message is a single-or
  multiple-line WTO by checking whether the message begins with
  'CSL'.  If it does, the message is a single line WTO.
  Otherwise, it is assumed to be a multi-line WTO.  This leads to
  the reported abend when the character data 'BPE0' is treated as
  a storage address when the exit attempts to process the message
  as if it were a multi-line WTO.
  
  This problem is only exposed if the optional CSL Unsolicited
  Message User Table, CSLZUMTU, is installed.  If this table is
  not present, CSLSXPR0 branches around the line of code that
  produces the ABEND0C4.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  Additional checking is added to CSLXBPR0 to correctly
  differentiate between single-and multi-line WTOs.  First, any
  message with the prefix 'BPE' is processed as a single line WTO.
  Additionally, any message in which flag WPLMCSFJ in byte
  WPLMCSF2 is not set is processed as a single line WTO.
