PH21007: COBOL V6.2. was inadvertently generating code to fix up bad signnibbles in zoned to zoned moves

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The sign nibble in the receiver is explicitly set to an
  appropriate value after the move, which is inconsistent with the
  behavior of programs compiled with pre-V5 compilers, which
  maintain the invalid sign nibble after the move.
  

Local fix

• Fix invalid data in your program.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.3 compiling and *
  *                 running programs compiled with the           *
  *                 ZONEDATA(NOPFD|MIG) option in effect and the *
  *                 following conditions occur:                  *
  *                 1. the program contains a MOVE statement     *
  *                 that moves a zoned decimal sender to a zoned *
  *                 decimal receiver                             *
  *                 2. the zoned decimal receiver has different  *
  *                 sign and/or length properties than the zoned *
  *                 decimal sender                               *
  *                 3. the zoned decimal sender contains an      *
  *                 invalid sign nibble.                         *
  ****************************************************************

  * RECOMMENDATION: Apply the IBM provided PTF.                  *
  ****************************************************************
  When option ZONEDATA(NOPFD|MIG) is in effect, the compiler was
  inadvertently generating code to fix up bad sign nibbles in
  zoned to zoned moves in situations where that wasn't being done
  in pre-V5 compilers.
  

Problem conclusion

• The compiler was updated to match the pre-V5 behavior for fixing
  sign nibbles for zoned to zoned moves when option
  ZONEDATA(NOPFD|MIG) is in effect.
  

Temporary fix
