NAME
tile c based forth-83 standard compiler and programming
environment
SYNOPSIS
forth [dpru size] [file ...] [a argument ...]
forth [dpru size] [file ...] [s start-symbol] [argument
...]
DESCRIPTION
forth uses a command syntax much like a compiler. The file
arguments are loaded before the interaction top loop is
started. A startsymbol may also be given as an argument
making forth act as a `compile-and-go' compiler of
applications. Any extra options or parameters passed to
forth may be accessed by the application. As extensions of
the Forth-83 Standard forth supports floating point
numbers, strings, multi-tasking, exceptions, private
definitions, argument binding and local variables and much
more. Written in C the kernel may be used as a general
purpose environment for interactive testing and
development of C-code.
To provide an interactive programming environment for
developing programs forth may be run as a sub-process to
GNU Emacs in a specialized forthmode. Source code may be
edited and directly tested by passing either a paragraph
of code or a whole buffer to forth from Emacs. The
forthmode also supports documentation retrieval and
automatic indentation of forth code, comments and
definitions.
An environment variable is used to specify file search
paths and support management of libraries of source code.
forth compiles faster than most compilers link with
approx. 70.000 lines per minute on a SUN-3/60 (and over
200.000 on a SUN-SPARCstation 1). Code is only saved in
source form. Loading all available library code takes
less than a second.
OPTIONS
ddictionary-size
Size of dictionary in bytes. Default allocation is
1024K bytes.
pparameters-stack-size
Size of foreground process parameter stack in cells
(32-bits). Default allocation is 256 cells.
rreturn-stack-size
Size of foreground process return stack in cells
(32-bits). Default allocation is 256 cells.
Version 3.33 August 16, 1990 1
TILE(1) TILE(1)
uuser-area-size
Size of foreground process user area in bytes.
Default allocation is 1024 bytes.
a argument ...
Allows access of the rest of the arguments. The
first arguments is the string forth.
s start-symbol
Defines the symbol to be used instead of the normal
interaction top-loop. The startsymbol becomes the
first argument and any further arguments may be
accessed by the application. The library contains
some examples of argument fetching functions.
LIBRARIES
The tile environment consists currently of five
directories with C kernel source, forth-83 source library,
test and example code, manuals and documentation. The
directory src contains all the C-level code and the GNU
emacs programming environment. The directory lib contains
Forth-83 source code modules, consisting of a number of
data modelling, and debugging tools, and high level multi-
tasking constructs such as semaphores, channels,
rendezvous and task types. Documentation of the source
code and the kernel are found in the directory man and in
the directory doc. These are use for handling manual
commands or documentation search in the programming
environment (in GNU emacs). Test programs for each
forth-83 source library code may be found in the directory
tst.

ENVIRONMENT
TILE Path for the tile directory structure.
A normal setting for a single user is
`$HOME/tile'.
TILEPATH Search path for library source files.
A normal setting is
Version 3.33 August 16, 1990 2
TILE(1) TILE(1)
`$TILE/lib:$TILE/tst' which will allow
the file include function in forth to
locate library source files in the
current directory ($PWD), the standard
library, and the test code library.
forth also looks for files at your
home directory ($HOME).
MANPATH Search path for manual source files.
Used by man for access of manual
pages. Setting this environment
variable to `$TILE/man:/usr/share/man'
will allow you to read the forth
manual pages.
GNU EMACS FORTH MODE
The GNU Emacs forth-mode supports interactive programming,
automatic indentation of source code, and documentation
search of the forth kernel and library within Emacs. To
allow automatic loading of the mode your .emacs file
should contain the following definitions;
(set-variable 'load-path
(append load-path
'(nil "~/tile")))
(setq forth-help-load-path '(nil "~/tile/doc"))
(setq auto-mode-alist
(append '(("\\.tst$" . forth-mode)
("\\.f83$" . forth-mode))
auto-mode-alist))
(autoload 'forth-mode "forth")
Further documentation about the forthmode may be found by
giving the command `M-x describe-mode' in Emacs.
BUGS
Bugs should be reported to mip@ida.liu.se. Bugs tend
actually to be fixed if they can be isolated, so it is in
your interest to report them in such a way that they can
be easily reproduced according to get newer version.
