.SH NAME
p2cc \- Pascal compiler using p2c
.SH SYNOPSIS
.B p2cc
[ options and files ]
.SH DESCRIPTION
.I P2cc
is a Pascal compiler that works by running
.I p2c,
the Pascal to C translator, followed by
.I cc,
the C compiler.
.PP
All command-line options and arguments are passed directly to
the C compiler, except that files ending with
.B .p
or
.B .pas
are passed through
.I p2c
first, and that the options listed below are interpreted specially by
.I p2cc.
As usual, programs made up of several source modules can be compiled
all on one
.I p2cc
command, or separately using
.IB p2cc "\ -c"
and then linked afterwards with a final
.I p2cc
command.
.SH OPTIONS
.TP
.B \-p2c
Translate
.B .p
and
.B .pas
files to C but do not compile the resulting
.B .c
files.  This is analogous to the
.B \-S
and
.B \-c
options of most C compilers, which stop with assembly language or
unlinked object files, respectively.
.TP
.BI \-p2c option
Pass
.I option
to
.I p2c
rather than to the C compiler.
.TP
.B \-O
This switch is passed on to the C compiler to enable optional
optimization of the program.  It also instructs
.I p2c
to do a few optimizations of its own, e.g., disabling certain
run-time range checks.
.TP
.BI \-I dir
The
.B \-I
switch is passed to both
.I p2c
and the C compiler, where it will identify places to look for
Pascal interface texts or C
.B .h
files, respectively.
.TP
.B \-v
Enable "verbose" mode.  This affects both
.I p2c
and the C compiler.
.SH ENVIRONMENT
The following environment variables may be used to affect the
operation of
.I p2cc.
.TP
.B P2CC_PAT
This variable holds a regular expression for recognizing the names
of Pascal files.  By default, it recognizes strings which end in
.B .p
or
.B .pas.
.TP
.B P2CC_CC
This holds the name of the command to run the C compiler.
Default is
.B cc.
.TP
.B P2CC_CCOPTS
This holds additional arguments to be passed to the
.B cc
command, before the names of any source files.
.TP
.B P2CC_CCOPTS2
These arguments are passed to the
.B cc
command
.I after
the names of source files.
.TP
.B P2CC_LIBP2C
This is the name of the
.B libp2c.a
file holding
.I p2c
runtime routines.  Its default is
.B \-lp2c,
which causes the linker to look for
.B libp2c.a
in the usual places for libraries.
.TP
.B P2CC_P2C
This holds the name of the command to run
.I p2c.
It is
.B p2c
by default.
.TP
.B P2CC_P2COPTS
These are arguments to be passed to
.I p2c
on the command line.  The default specifies
.B \-comp,
which set the defaults for various
.I p2c
configuration options to be more suitable for compilation rather
than translation, and
.B \-local,
which sets other options to work on the assumption that the output
from
.I p2c
will be compiled and run on the same type of machine that ran
.I p2c
itself.
.TP
.B P2CC_SUFFIX
This is the suffix to use for the names of temporary C source files.
The default is
.B ..c,
ensuring that
.I p2c
will not inadvertently erase
.B .c
files in the same directory as the Pascal source files.  Note that
if the
.B \-p2c
option is used, the suffix is forced instead to
.B .c
since the user has explicitly asked for C source files.
