Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Message CSQU541E is incorrectly issued if using the ARRAYDB2
  function of utility CSQUZAP with an ARRAY(LH) NUMBER greater
  than 64, an ARRAY(STRUCTURE) NUMBER greater than 64, or an
  ARRAY(QMGR) NUMBER greater than 32.

Problem summary

  * USERS AFFECTED: All users of IBM MQ for z/OS Version 9       *

  ****************************************************************
  * PROBLEM DESCRIPTION: CSQUZAP DB2ARRAY would fail and issue   *
  *                      message CSQU541E when using a NUMBER    *
  *                      value above 64 for ARRAY(LH) and        *
  *                      ARRAY(STRUCTURE) and a NUMBER value     *
  *                      above 32 for ARRAY(QMGR).               *
  ****************************************************************
  CSQUZAP would incorrectly validate the value of NUMBER by
  checking it does not exceed the length of the array in bytes,
  however NUMBER represents a bit in the array not a byte, so
  the length of the array should be calculated in bits not bytes.
  

Problem conclusion

• CSQUZAP has been corrected to calculate the length of the array
  in bits. The user will now correctly receive a CSQU104E message
  when the value of NUMBER exceeds the max allowable value.
  Message CSQU541E is no longer incorrectly issued.
