PI67356: DSECT UTILITY DUPLICATION FACTOR OF ZERO GENERATING VARIABLE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The DSECT utility is generating an unexpected variable
  definition for an ASM DS statement using a duplication factor of
  zero, which is used to align data and should not generate a
  variable definition.

   Use the DS instruction to align the instruction or data that
   follows, on a specific boundary. You can align the location
   counter to a doubleword, a fullword, or a halfword boundary by
   using the correct constant type (for example, D, F, or H) and a
   duplication factor ofzero. No space is reserved for such an
   instruction, yet the data that follows is aligned on the
   correct boundary.

     === TESTCASE ===
  TEST       DSECT
  FIELD1     DS   H
  TESTEND    DS  0F  fullword aligned end
             END
  
  
     === INCORRECT OUTPUT ===
  
  struct TEST {
    short int      FIELD1;
    unsigned char  _filler1[2];
    int            TESTEND;     /* fullword aligned end */
    };
  
  - The 'int TESTEND;' variable is unexpected
  

Local fix

• Manually edit out unexpected ASM
