[REBOL] Parsing command line arguments Re:

[jeff]

       Howdy, Garold:

       Command line args that use - or + can be quoted. If you
       need quotes, at least under unix, you can escape the
       quotes.

       Using the following script which I called "rargs":

    #!/usr/local/bin/rebol -q
    REBOL [Title: "Rargs"]

    foreach item [
        system/options/args
        system/script/args
    ][ print [mold :item "==" item]]


You can see some examples:

    rargs print \"hello\"

    system/options/args == print "hello"
    system/script/args == print "hello"


    rargs \"+-\"
    
    system/options/args == "+-"
    system/script/args == "+-"

    or...

    rargs {+-}

    system/options/args == {+-}
    system/script/args == {+-}

    If you're running under windows, I'm not sure what the
    comparable .bat file for above would be like.  Would it
    just call rebol on the script you wanted? Maybe so... Not
    sure about what you'd do under mac or amiga to do shell
    script kind of stuff.  Maybe someone will educate me. :-)

    Oddly enough, I just wrote a little article on using REBOL
    for shell scripts:
