PQ88205: WITH SELECT FUNCTION THERE IS IMS ABEND0C4 RISK WHEN USING A WILDCARD FOR ANY PARM WITH INCLUDE/EXCLUDE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With the QCF SELECT function (IQCSELCT) there is an ABENDS0C4
  risk to the IMS control region when using INCLUDE or EXCLUDE
  parms such as DESTINATION=, LUNAME= or other parms with the
  wild card (*) asterisk designation. Using the wild card only
  before this APAR will mean nothing will be selected and
  the IQCSELCT step can get the possible abend.
  .
  IMS recently completed PQ86376 where the use of (*) on the same
  parms for QCF functions BROWSE, QUERY and UNLOAD caused an
  ABEND0C4 in IMS. With the IMS APAR these functions work properly
  for QCF now.  The reason this APAR is needed is that the SELECT
  function does a compare reading log records whereas the other
  functions only pass the value to IMS to do the compare.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of QCF, that execute SELECT step to    *
  *                 extract messages for reinserting.            *
  ****************************************************************
  * PROBLEM DESCRIPTION: When using wildcard '*' to include      *
  *                      messages by names- no check was done to *
  *                      check that '*' is the only character    *
  *                      entered. If the '*' is the only         *
  *                      character, the length of the string is  *
  *                      set to 0. Then - to prepare the         *
  *                      executable length of CLC instruction-   *
  *                      1 is subtracted from the length value.  *
  *                      Compare statement works with length of  *
  *                      255- which may cause a 0C4, or "not     *
  *                      equal" condition followed by reject of  *
  *                      the record (in case of '*'- all values  *
  *                      should be accepted).                    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Wildcard character - if it is the only character used in INCLUDE
  for names -could cause 0C4 or (if not a 0C4 occures ) all
  records are rejected, which is not true (all records should be
  accepted). Program is fixed to accept all values when '*' is
  entered.
  

Problem conclusion

• Program is changed to accept all values if the wildcard '*' is
  used.
