.SH NAME

GForth
.SH SYNOPSIS

\fCgforth\fR [initialization options] [image-specific options]
.SH DESCRIPTION

\fBGForth\fR is a fast and portable implementation of the Forth
programming language. For details read the manual.
.SH ENVIRONMENT VARIABLES

\fCGFORTHPATH\fR
gives the search path for source files.
.SH EXAMPLES

\fCgforth\fR

starts the system and goes into interactive mode.

\fCgforth file1 file2 \-e bye\fR

loads and interprets the files \fCfile1\fR and \fCfile2\fR, then
exits.
.SH OPTIONS

.BI "\-\-image\-file " "file"
.TQ "\-i " "file"
Loads the Forth image
.I file
instead of the default \fCgforth.fi\fR.
.TP
.BI "\-\-path " "path"
.TQ "\-p " "path"
Uses
.I path
for searching the image file and Forth source code
files instead of the default in the environment variable
\fCGFORTHPATH\fR
or the path specified at installation time (typically
\fC/usr/local/lib/gforth:.\fR. A path is given as a 
.BR : -separated
list.
.TP
.BI "\-\-dictionary\-size " "size"
.TQ "\-m " "size"
Allocate
.I size
space for the Forth dictionary space instead of
using the default specified in the image (typically 256K). The
.I size
specification consists of an integer and a unit (e.g., \fC4M\fR).
The unit can be one of \fCb\fR (bytes),
\fCe\fR (element size, in this case Cells),
\fCk\fR (kilobytes), and
\fCM\fR (Megabytes). If no unit is specified,
\fCe\fR is used.
.TP
.BI "\-\-data\-stack\-size " "size"
.TQ "\-d " "size"
Allocate
.I size
space for the data stack instead of using the
default specified in the image (typically 16K).
.TP
.BI "\-\-return\-stack\-size " "size"
.TQ "\-r " "size"
Allocate
.I size
space for the return stack instead of using the
default specified in the image (typically 16K).
.TP
.BI "\-\-fp\-stack\-size " "size"
.TQ "\-f " "size"
Allocate
.I size
space for the floating point stack instead of
using the default specified in the image (typically 16K). In this case
the unit specifier
\fCe\fR
refers to floating point numbers.
.TP
.BI "\-\-locals\-stack\-size " "size"
.TQ "\-l " "size"
Allocate
.I size
space for the locals stack instead of using the
default specified in the image (typically 16K).

.TP
.BI "\-\-evaluate " "forth"
.TQ "\-e " "forth"
Evaluates the
.I forth
code. This option takes only one argument; if you want to evaluate
more Forth words, you have to quote them or use several \fC-e\fRs.  To
exit after processing the command line (instead of entering
interactive mode) append \fC-e bye\fR to the command line. This is an
image-specific option.
