PI11987: MFS REVERSAL ABEND0C1 WHEN PROCESSING SPECIFIC TYPE OF DOF

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND0C1 occurs when MFS Reversal processes an MFS library
  member DOF which meets all of the following conditions:
   - DEV TYPE=SCS1
   - DIV TYPE=OUTPUT
   - The DOF doesn't have an inner table, tab buffer
  .
  MFS Reversal also has the following problems:
   - MFS source is decoded without MID and MOD if FABV0030W or
  FABV0031W is issued while processing the member just before.
   - EGCS literal field for DEV TYPE=SCS1 is decoded as normal
  literal field

  (1) This APAR fixes the following two problems when processing
      DOF for SCS1 device:
  
  (1-1) When one of the following conditions met, MFS Reversal and
        MFS Compare tries to process horizontal tab even though
        it is an unnecessary process and gets ABEND0C1.
  
   - "HTAB=(x,a,HT=(a))" is specified on a DEV statement for SCS1
     device and the first "a" as column position of the left
     margin and the second "a" as horizontal tab stop location
     have the same value.
  
   - "HTAB=(x,a,HT=(b)),WIDTH=b" is specified on a DEV statement
     for SCS1 device and the first "b" as horizontal tab stop
     location and the second "b" as maximum line width have the
     same value.
  
  (1-2) Incorrect MFS source is decoded and compared for the
        following cases:
  
   a. MFS Reversal decodes an garbage value "13" as the latest
      value of HT parameter in HTAB parameter on a DEV statement
      for SCS1 device like this:
      "HTAB=(x,y,HT=(z1,z2,...,zn,13))"
      MFS Compare compares the garbage value.
  
   b. MFS Reversal decodes a DFLD statement for SCS1 device
      as a normal literal even if originally defined as an EGCS
      literal.
      MFS Compare compares the DFLD statement as a normal literal.
  
   c. MFS Reversal decodes incorrect value as position value of
      POS parameter on a DFLD statement of EGCS literal for
      SCS1 device.
      MFS Compare compares the incorrect value.
  
  (2) This APAR fixes the following two problems when MFS Reversal
      or MFS Compare issues FABV0030W or FABV0031W:
  
  (2-1) MFS Reversal does not generate statements for MID and MOD
        when FABV0030W or FABV0031W is issued while processing a
        member just before.
        MFS Compare does not compare statements for MID and MOD
        when FABV0030W or FABV0031W is issued while processing a
        member just before.
  
  (2-2) MFS Reversal creates a garbage member '........' which
        includes incomplete MFS source in the data set specified
        by MFSSRCE DD when FABV0030W or FABV0031W is issued.
        MFS Compare creates the garbage member in the data set
        specified by MFSSRCE DD and MFSSRCE2 DD and compare them.
