PH50301: REQUEST TO HAVE NUMCHECK(ZON(LAX)) IGNORE NUMERIC TO ALPHANUMERIC MOVES

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• This is a request to have NUMCHECK(ZON(LAX)) ignore numeric to
  alphanumeric MOVEs.  Note that a group data item is considered
  to be an alphanumeric data item, so in a numeric MOVE to a group
  data item, the sender's data would not be checked for validity
  under NUMCHECK(ZON(LAX)).

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.2 compiling and  *
  *                 running programs compiled with the           *
  *                 NUMCHECK(...,ZON(LAX)) option in effect and  *
  *                 where the programs contain a MOVE statement  *
  *                 with a zoned decimal sender containing       *
  *                 invalid data and an alphanumeric receiver.   *
  ****************************************************************
  * PROBLEM DESCRIPTION: Runtime abend or message due to         *
  *                      NUMCHECK violation.                     *
  ****************************************************************
  * RECOMMENDATION: Apply the IBM-provided PTF.                  *
  ****************************************************************
  The NUMCHECK(...,ZON(LAX)) option is intended to provide more
  relaxed checking of zoned decimal senders where it is safe to do
  so. Since moving a zoned decimal data item to an alphanumeric
  data item is not a numeric operation, the checking should be
  relaxed when ZON(LAX) is in effect because such an operation is
  a common pattern in some user code (e.g., moving a zoned decimal
  data item initialized with LOW-VALUES to an alphanumeric
  receiver).
  

Problem conclusion

• The compiler was updated to avoid generating runtime checking
  code of zoned decimal senders in MOVE statements when the
  receiver is an alphanumeric data item and NUMCHECK(...,ZON(LAX))
  is in effect.
