  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  This APAR fixes the following problems:
  
  1. MFS Reversal goes into a loop when an original MFS source for
     a DPM-A output device has a FORMS parameter on a DEV
     statement.
  
  2. MFS Reversal generates an incorrect literal value as a FORMS
     parameter on a DEV statement when an original MFS source has
     the following parameters:
     - A FORMS parameter is specified on a DEV statement for a
       DPM-A output device.
     - OPTIONS=MSG is specified on a DIV statement for output.
  
  3. MFS Reversal tries to convert a MID and gets ABEND0C4 in the
     FABVMID module at offset +X'E80' when an original MFS source
     has the following parameters:
     - A PEN parameter, a CARD parameter, or a PFK parameter is
       specified on a DEV statement for a 3270 display device.
     - The field name that is specified on the PEN parameter, the
       CARD parameter, or the PFK parameter is not referred to by
       input MFLD statements.
  
  4. MFS Reversal does not generate an input MFLD statement when
     an original MFS source has the following parameters:
     - A PRN parameter is specified on a DIV statement for a 3270
       display device.
     - An input MFLD statement references the field name that is
       specified on the PRN parameter.
  
  5. MFS Reversal generates an incorrect value as a POS parameter
     on a DFLD statement for a 3270 device when the column number
     of the POS parameter is the maximum value in an original MFS
     source.
  
  6. MFS Reversal incorrectly generates an ATTR parameter on an
     output MFLD statement even when the ATTR parameter on the
     MFLD statement is not specified in an original MFS
     source.
  
  7. MFS Reversal generates an incorrect value as an LTH parameter
     on an input MFLD statement when an ATTR=nn on the MFLD
     statement is specified in an original MFS source.
  
  These problems also can occur in MFS Compare utility.
