NAME
sci - Scheme interpreter
SYNTAX
sci [ option ]
DESCRIPTION
The sci command invokes a Scheme interpreter. The language accepted by
this interpreter is that defined in the essential portions of the
Revised4 Report on the Algorithmic Language Scheme, with minor
constraints and some additions. The Scheme interpreter is written in
Scheme which has then been compiled using the Scheme-to-C compiler,
scc.
OPTIONS
These options are accepted by sci.
-e Echo text read from the standard input file on the
standard output file.
-emacs Scheme interpreter is controlled by GNU emacs.
-nh Do not print the interpreter version header on the
standard output file.
-np Do not prompt for input from the standard input file on
the standard output file.
-q Do not print the result of each expression evaluation.
-scgc statflag
Enables garbage collection statistics. If set to 1,
then garbage collection statistics will be printed. The
default is 0, that will result in no statistics.
-sch heap Specifies the initial size of the heap in megabytes.
The default heap size is 4 MB. The maximum heap size
allowed is 1000 MB.
-scl percent Specifies the percent of the heap allocated after a
generational garbage collection that will force a full
collection. The default is 40%.
-scm main Specifies the function that should be used instead of
the predefined "main". The function name must be
entered in the correct case, i.e. letters typically
upshifted.
-scmh heap Specifies the maximum heap size in megabytes. The
default is five times the initial size of the heap.
ENVIRONMENT VARIABLES
The items controlled by -sc.. flags can also be controlled by
environment variables. If both the flag and the environment variable
are provided, then the flag’s value will be used.
SCGCINFO Controls the reporting of garbage collection statistics
to the standard error file. If set to 1, then garbage
collection statistics will be printed. The default
setting is 0 that will not print the statistics.
SCHEAP Specifies the initial size of the heap in megabytes.
The default heap size is 4 MB. The maximum heap size
allowed is 1000 MB.
SCLIMIT Specifies the percent of the heap allocated after a
generational garbage collection that will force a full
collection. The default is 40%.
SCMAXHEAP Specifies the maximum size of the heap in megabytes.
The default value is five times the initial heap size.
FILES
The interpreter is one a.out file with the name sci. All files
associated with the interpreter are found in the directory
.../schemetoc/scrt.
