NAME
ocaml - The Objective Caml interactive toplevel
SYNOPSIS
ocaml [ -unsafe ] [ -I lib-dir ] [ object-files ] [ script-file ]
DESCRIPTION
The ocaml(1) command is the toplevel system for Objective Caml, that
permits interactive use of the Objective Caml system through a read-
eval-print loop. In this mode, the system repeatedly reads Caml phrases
from the input, then typechecks, compile and evaluate them, then prints
the inferred type and result value, if any. The system prints a #
(sharp) prompt before reading each phrase.
A toplevel phrase can span several lines. It is terminated by ;; (a
double-semicolon). The syntax of toplevel phrases is as follows.
The toplevel system is started by the command ocaml(1). Phrases are
read on standard input, results are printed on standard output, errors
on standard error. End-of-file on standard input terminates ocaml(1).
If one or more object-files (ending in .cmo or .cma
) are given, they are loaded silently before starting the toplevel.
If a script-file is given, phrases are read silently from the file,
errors printed on standard error. ocaml(1) exits after the execution
of the last phrase.
OPTIONS
The following command-line options are recognized by ocaml(1).
-I directory
Add the given directory to the list of directories searched for
source and compiled files. By default, the current directory is
searched first, then the standard library directory. Directories
added with -I are searched after the current directory, in the
order in which they were given on the command line, but before
the standard library directory.
-unsafe
Turn bound checking off on array and string accesses (the v.(i)
and s.[i] constructs). Programs compiled with -unsafe are there-
fore slightly faster, but unsafe: anything can happen if the
program accesses an array or string outside of its bounds.
ENVIRONMENT VARIABLES
LC_CTYPE
If set to iso_8859_1, accented characters (from the ISO Latin-1
character set) in string and character literals are printed as
