NAME

       jocaml - The JoCaml interactive toplevel

SYNOPSIS

       jocaml [ -unsafe ] [ -I lib-dir ] [ object-files ] [ script-file ]

DESCRIPTION

       The  jocaml(1) command is the toplevel system for JoCaml, that permits interactive use of the JoCaml system through a read-eval-print loop.
       In this mode, the system repeatedly reads Caml phrases from the input, then typechecks,	compiles  and  evaluates  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 jocaml(1).  Phrases are read on standard input, results are printed on standard output,
       errors on standard error. End-of-file on standard input terminates jocaml(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.  jocaml(1) exits after the  execution
       of the last phrase.

OPTIONS

       The following command-line options are recognized by jocaml(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 therefore
	      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  is;
	      otherwise, they are printed as decimal escape sequences.

       TERM   When  printing  error  messages,	the toplevel system attempts to underline visually the location of the error. It consults the TERM
	      variable to determines the type of output terminal and look up its capabilities in the terminal database.
