WESTAT PL/I PREPROCESSOR

    This directory contains a VAX implementation of a preprocessor
for the PL/I language similar to that available in IBM's Optimizing
Compiler implementation.  Files are:

PLIMAC.EXE    executable image, should be installed as a foreign
              command by
 
                 $ ASSIGN (this directory) WES$PLIMAC
                 $ PLIM*AC:==$WES$PLIMAC:PLIMAC

PLIMAC.HLP    a help file with many examples

NEATEN.PLM    a sample preprocessor macro similiar to the example
              in Barnes' book PL/I for Programmers 

NEATEN.PLI    PLIMAC output produced from NEATEN

LAYOUT.PLM    examples and output, FORTRAN.FOR produced with the
LAYOUT.PLI    /FORTRAN/OUT=FORTRAN.FOR options
FORTRAN.PLM
FORTRAN.FOR
WHILTST.PLM
WHILTST.PLI

    PLIMAC can be used as a preprocessor for a number of other languages
including FORTRAN and MACRO.  It seems to be a more efficient 
implementation than the IBM preprocessor.  We would appreciate reports
on any bugs found or comments on implementation style.  Contact Tip Dow
or Allan Jaworski at Westat (301)-251-1500.
