NAME

       sisc - Second Interpreter of Scheme Code

SYNOPSIS

       sisc [ option ...  ] [ argument ...  [ -- [ program-option ...  ] ]

DESCRIPTION

       SISC,  the  Second Interpreter of Scheme Code, is an extensible Java based interpreter of the Scheme language as described in the Revised^5
       Report on the Algorithmic Language Scheme and adds numerous extensions including Java integration.

STARTUP FILE AND EXPRESSION OPTIONS

       -c name

       --call-with-args name
	      Calls the top-level procedure name with the remaining command-line arguments after the -- delimiter.

       -e expr

       --eval expr
	      Evaluates the provided expression.

       -x

       --no-repl
	      Instructs SISC to run the command line and then exit without entering the REPL.

       -h heap-file

       --heap heap-file
	      Specifies that heap-file should be used as the initial heap image.

       -p config-file

       --properties config-file
	      Specifies a Java property file that contains application properties.

       -l [<host>:]<port>

       --listen [<host>:]<port>
	      Server Mode.  Listen on <host>/<port> for REPL connections.

COMMAND LINE BEHAVIOR

       The commandline is processed in the following manner.

       First, the entire command line is processed, noting the settings of each switch and accumulating all  Scheme  source  files  and  arguments
       after the end of options sequence.

       Second, the heap file is loaded.

       Third, each Scheme source file is loaded in the order they occured on the command line. Errors are noted.

       Fourth, if present, the expression in an --eval switch is evaluated. Errors are noted.

       Fifth,  if  present, named function in a --call-with-args switch is applied to the arguments after the end of options sequence.	Its return
       value is noted.

       Sixth, --no-repl was not specified, the REPL is invoked.

       Finally, if the REPL was run if its return value is an integer, that integer is returned as SISC's overall return code. If the REPL was not
       run,  and any return code supporting step above was run, the most recent return code is returned. If no return code step was performed, but
       a success/failure step was performed, 1 is returned if any failures occured, 0 otherwise.

EXECUTABLE SCRIPTS

       SISC supports all the required SRFI-22 bootstraps, consult the body of SRFI-22 for more information about  using  it  to  write	executable
       Scheme programs.

NAME

       scheme48 - a Scheme interpreter

SYNOPSIS

       scheme48 [-i image] [-h heapsize] [-a argument]

DESCRIPTION

       scheme48  is  an implementation of the Scheme programming language as described in the Revised^5 Report on the Algorithmic Language Scheme.
       A runnable system requires two parts, an executable program that implements the Scheme 48 virtual machine, and an image	that  is  used	to
       initialize  the	store  of  the	virtual  machine.  scheme48 is a shell script that starts the virtual machine with an image that runs in a
       Scheme command loop.

       The scheme48 command loop reads Scheme expressions, evaluates them, and prints their results.  It also executes commands, which are identi-
       fied by an initial comma character.  Type the command ,help to receive a list of available commands.

       The  meaning  of  the  -h option depends on the type of garbage collector that was chosen at configuration time.  If heapsize is a positive
       number, it specifies the number of words that can be live at any given time.  One word is four bytes.  Cons cells are currently 3 words, so
       if you want to make sure you can allocate, say, a million cons cells, you should specify -h 3000000 (actually a little more, to account for
       the initial heap image and breathing room).

       If you specify a maximum smaller than the memory needed to load the image file, the maximum is increased accordingly and a message is writ-
       ten to the console.

       For  the  BIBOP garbage collector, heapsize may be 0.  This means the heap will possibly keep growing until your system runs out of memory.
       Because of this risk, a warning message is written to the console if you specify -h 0.

       The ,dump and ,build commands put heap images in files.	The -i option causes the initial heap image to be taken from file image.   The	-a
       option  causes a list of strings to be passed as the argument to an image generated using the ,build command.  The first argument to ,build
       is a procedure that is passed the arguments following -a and which should return an integer (which is the return value  of  the	Scheme	48
       process).

	    > ,build (lambda (a) (display a) (newline) 0) foo.image
	    > ,exit
	    $ scheme48 -i foo.image -a mumble
	    mumble
	    $

FILES

       /usr/lib/scheme48-1.`cat ./build/minor-version-number`/scheme48vm
					       the virtual machine.

       /usr/lib/scheme48-1.`cat ./build/minor-version-number`/scheme48.image
					       the default image.
