.SH DESCRIPTION
.LP
.I fpc
is a fast
.B Pascal
compiler. It translates 
.B Pascal
programs
into cc(1)-compatible relocatable object modules, and does so in one pass.
Then, if the \fB\-c\fP flag is not given,
.I fpc
offers the object modules to a link-editor,
to create an executable binary.
.LP
.I Fpc
accepts several types of filename arguments.  Files with 
names ending in
.B .p
are taken to be 
.B Pascal
source programs. 
They are compiled, and the resulting object module is placed in the current
directory.
The object module is named after its source file, the suffix
.B .o
replacing 
.BR .p
in the name of the object.
A file with suffix
.B .p
is passed through the C preprocessor if it begins with a '#'.
.LP
Other arguments refer to loader options,
object modules, or object libraries.
Unless the
.B \-c
flag is given, these modules and libraries, together with the results of any
specified compilations, are passed (in the order given) to the
link-editor to produce
an output file named
.IR a.out .
You can specify a name for the executable by using the
.B \-o 
option.
.LP
If a single 
.B Pascal
program is compiled and loaded all at once, the object module
file is deleted.
.SH OPTIONS
.LP
The \fB\-l\fIlib\fR, \fB\-d\fP, \fB\-n\fP, \fB\-N\fP,
\fB\-r\fP, \fB\-s\fP, \fB\-S\fP, \fB\-i\fP, and \fB\-u\fP options are
passed to the link-editor program.
The \fB\-u\fP option takes an extra argument.
.IP \fB\-c\fP
.br
Suppress the loading phase of the compilation, and force an object module to
be produced, even if only one program is compiled.
A single object module can be named explicitly using the
.B \-o
option.
.IP \fB\-D\fIname\fR\fB=\fIdef\fR
Define a symbol
.I name
to the 
preprocessor, as if by "#define".
.IP \fB\-D\fIname\fR
.br
same as \fB\-D\fIname\fB=1\fR.
.IP \fB\-I\fIpathname\fR
.br
Add
.I pathname
to the list of directories in which to search for
.B #include
files with filenames not beginning with slash.
The preprocessor first searches for
.B #include
files in the directory containing
.I sourcefile,
then in directories in
.B \-I
options, and finally, in
.I /usr/include.
.IP "\fB\-o \fIoutput\fR"
Name the final output file
.I output.
.IP \fB\-O\fP
.br
Use a version of the compiler that is just a bit slower, but produces
better code.
.IP \fB\-U\fIname\fR
.br
Remove any initial definition of
.I name.
.IP \fB\-v\fP
.br
Verbose. Print the commands as they are executed.
.IP \fB\-vn\fP
.br
Verbose, no execute. Only print the commands, do not execute them.
.IP \fB\-L\fP
.br
do not generate code to keep track of
the current location in the source code.
.IP \fB\-w\fP
.br
suppress warning messages.
.IP \fB\-d\fP
.br
allow for "long"s.
.IP \fB\-i\fInum\fR
.br
set size for integer sets. By default, the set size is the word size.
.IP \fB\-C\fP
.br
distinguish between lower case and upper case. Normally, upper case letters
are considered equal to their lower case counterpart.
.IP \fB\-t\fP
.br
trace calls and exits of procedures and functions.
.IP \fB\-R\fP
.br
disable all range-checks.
.IP \fB\-A\fP
.br
enable extra array bound checks. Unfortunately, the back-end used for this
compiler is a bit sloppy, so extra array bound checks are needed if you want
detection of array bound errors.
.IP \fB\-a\fP
.br
disable assertions. Assertions are skipped instead of evaluated.
.IP "\fB\-U+\fP, \fB\-u+\fP"
.br
allow for underscores within identifiers. Identifiers may not start
with an underscore, even if this flag is given.
.IP \fB-s+\fP
.br
allow only standard 
.BR Pascal .
This disables the \fB\-c+\fP, \fB\-d\fR, \fB\-u+\fR,
\fB\-U+\fR and \fB\-C\fR options.
Furthermore, assertions are not recognized at all.
.IP \fB-c+\fP
.br
allow C-like strings. This option is mainly intended for usage with
C-functions. This option will cause the type 'string' to be known.
.IP \fB\-M\fIcompiler\fR
.br
use \fIcompiler\fR as Modula-2 compiler instead of the default.
