By Bill Bereza  bereza@beech.csis.gvsu.edu  ac368@leo.nmc.edu

    no longer contains any code from RXBlank by Brian C. Berg,
    but thanks for the idea!


Installation:
        You'll need rexxarplib.library in libs: (It's available in many places)
        Then copy libs/RexxDosSupport.library to libs:
            (I included this because it isn't available everywhere)

        Then copy rndfile where ever you put you ARexx scripts.

Usage: rndfile Paths/M,Pattern/K,Command/K,CmdOptions/K,ALL/S,DIRS/S,FILES/S

       You do *not* need to put a '/' at the end of the Path.

    Paths/M     :   Specify any number of paths for rndfile to search through.
                    e.g. Work:Docs/
                    Default is the current directory.

    Pattern/K   :   An Arp pattern for rndfile to apply to the
                    list of files/dirs.
                    e.g. s#?.txt
                    Default is '~(#?.info)' No info files.

    Command/K   :   A program that rndfile will run on the chose file.
                    e.g. PPShow
                    Default is the enviroment variable DefRndCmd or 'c:list'
                    You can set your own default command with:
                        setenv DefRndCmd <command>

    CmdOptions/K:   Options to pass to the Command program.
                    e.g. SCREEN
                    Defaults to null string. (Nothing)

    ALL/S       :   Allow directories OR files to be chosen.
                    This is the default option.

    DIRS/S      :   Allow only directories to be chosen.

    FILES/S     :   Allow only files to be chosen.

Examples:
    RX rndfile
        uses default command 'c:list' on a file in the current directory

    RX rndfile Sounds:Samples/ Pictures:Things Command=delete All
        uses delete command on a random File OR Directory in those dir

    RX rndfile Sounds:Samples/ Command=Multiview CmdOptions="SCREEN BACKDROP"
        uses Multiview program with SCREEN and BACKDROP options
        in Sound:Samples/

History:    2.10    Just a few small additions.
                +   You can now have multiple paths. (See Examples)
                +   Now will read the default command from the env-variable
                    DefRndCmd.
            2.00    Hooboy! Completely re-wrote the program. It's like a
                    completely new program.
                +   Replaced ugly argument parsing structure with
                    ReadArgs() from RexxDosSupport.library.
                +   Now I use a real template.
                +   Replaced '.info' removing routines with FileList()
                    from rexxarplib.library.
                -   Now also checks for ':' instead of just '/'
                    No more 'Can't find Path SYS:/'

            1.10    Fixed instructions/comments

            1.00    I wrote this for the Amiga users on alt.tv.animaniacs
                    so they could play a collection of 'Wheel of Morality'
                    samples. Unfortunately, I wrote this before looking at
                    the sample collection. This program is useless for that.
                    But it did make a useful utility.

ToDo:       Some optimization should be done in the big 'do' loop.
            What more do you want? :) Send e-mail if you have a
            suggestion.

            Maybe get an ARexx compiler and compile it?

            I would like to use a better implementation of ReadArgs().
            I have one, but it would require a few changes.
