PI53098: PL/I MQ STRUCTURES ARE USING INIT(NULL()) INSTEAD OF INIT(SYSNULL())

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The PL/I declarations of MQ structures in SYS1.SCSQPLIC are
  using the old built-in function NULL() instead of SYSNULL().
  

Local fix

• n/a

  * PROBLEM DESCRIPTION: PL/I programs that include MQ control   *
  *                      block definitions from SCSQDEFS and/or  *
  *                      SCSQPLIC libraries have pointer         *
  *                      variables initialized with function     *
  *                      null().                                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  PL/I MQ control block definitions use function null() to
  initialize pointer variables with value 'FF000000'bx. This is
  not desirable because the queue manager won't recognize fields
  initialized in this way as null pointers, and instead will treat
  them as a valid addresses.
  

Problem conclusion

• PL/I MQ copy books have been changed to initialize pointer
  variables with function sysnull() which sets value '00000000'bx.
