       jocaml - The JoCaml interactive toplevel


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


       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.


       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.

              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.


              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.
