PH11975: MFS REVERSAL/COMPARE MAY CAUSE ABENDS0C1 AFTER PROCESSING A DOF FOR 3270P WHEN GARBAGE DATA FOUND

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• While MFS Reversal/Compare utility processing a MFS member
  which is a DOF(Device output format) for 3270P device with
  garbage data between SECTION FIELD LINKAGE ENTRIES and FIELD
  DESCRIPTOR, the utility breaks internal table or internal
  workspace. It may cause building incorrect MFS source for the
  DOF and also cause ABENDS0C1 or the infinite loop for
  processing another member with broken internal table or
  internal workspace.

  This APAR fixes Reversal/Compare utility not to cause ABENDS0C1.
  
  While MFS Reversal/Compare utility processing a MFS member which
  is a DOF(Device output format) for 3270P device with garbage
  data between SECTION FIELD LINKAGE ENTRIES and FIELD DESCRIPTOR,
  the utility breaks internal table or internal workspace.
  It may cause building incorrect MFS source for the DOF and also
  cause ABENDS0C1 or the infinite loop for processing another
  member with broken internal table or internal workspace.
  
  MFS Reversal/Compare utility has been fixed to skip garbage data
  for 3270P device.
