Changes
=======

PRTLIB version 1.1 has undergone some changes since the initial
release version 1.0.  The most significant was the addition of
four (4) new printer codes to the database.  The following
#xtranslates have been added to PCODES.CH:

 PAT_DWDHON    =>27
   Turn double wide/high print on
 PAT_DWDHOFF   =>28
   Turn double wide/high print off
 PAT_FL12      =>29
   Set form length to 12 inches
 PAT_FL11      =>30
   Set form length to 11 inches

The above codes were added at the request of registered users of
PRTLIB.  The double wide/high codes were necessary since some
printer models could not be set in this mode by sending the
double wide code followed by the double high code.

The form length 11 and 12 inch form length codes are useful for
dot matrix printers when printing labels.  The most common
continuous label sheets come in twelve inch lengths.  The twelve
inch form length code allows the EJECT command to maintain proper
label alignment.  The eleven inch form length code is necessary
to reset the printer for normal form length printing.

The structure for PAT_DEFS.DBF has been modified.  Four new
fields have been added to accommodate the printer codes above. 
If you have not modified the original PAT_DEFS.DBF that you
received with the original release, simply overwrite the original
files with the replacements.

If you have modified the database (added, changed definitions),
you can do one of either two things.

1.   Zap the new PAT_DEFS.DBF provided with the new structure and
     then append from your old modified database.  Then you
     should recreate the index (just delete PAT_DEFS.NTX, the
     next time the system is started by a call to INITPAT(), it
     will be created).

2.   Modify the structure of your old database by adding the
     following fields:

     Field  Field Name  Type       Width    Dec
        29  DWDH_ON     Character     30 
        30  DWDH_OFF    Character     30 
        31  FL11        Character     30 
        32  FL12        Character     30 

The following files have changed:
PCODES.CH           header file for printer code array subscripts
PAT_DEFS.DBF        Database of printer definitions
README.TXT          Introduction, documentation and registration
                    information
PAT.PRG             Main menu for demo program, shows
                    initialization
