        "Use which chainring"
        Sets this page up to use the gear inch values as set up
        on F5 for the chainring value entered here.  If this
        is set to 1 then this page will use the gear ratios
        for the first chainring to make the table.  If set to
        2 then it will use the larger chainring, etc.

        "Beginning rpm of crank."
        Allows the user to determine when the table will start
        calculating the speed for a given crank rpm.

        "Stopping rpm of crank."
        Allows the user to determine when the table will stop
        calculating the speed for a given crank rpm.

        "Increment rpm of crank by."
        Allows the user to determine jumps in the crank rpm.

        "Make a table to screen."
        Does the calculation and displays the results to the screen
        one page at a time.

        "Directory of output files."
        Provides an easy way to see what files already exist.
        The user is prompted to edit the mask or if "Enter" is
        pressed the current mask will be used.

        "File to act on."
        This is the file name that this page will use to write to,
        print, or delete.

        "Write the table to a file "
        Writes the same thing as "Make a table to screen" to the
        above file but without any "press any key" prompts in it.

        WARNING:
        THERE MUST BE ENOUGH AVAILABLE MEMORY IN YOUR MACHINE
        FOR THE FOLLOWING TO WORK.  (If you are calling this
        program from another there may not be enough left
        for these to dynamically use the extra memory that
        they need.)

        "View file"
        Allows the user to look at the data without going to DOS.
        (The "press any key" phrases are not really in the file.)

        "Erase file"
        Deletes the file if it is found.  No caution is provided.
        WARNINGS:
          1.  It just deletes the file.  No "are you sure" stuff
              here!   ( Just write it again.)
          2.  If the command to "Erase" the file is given too soon
              after the "Print" command then it is likely that
              only part of the file will be printed.
              If the file is a longer file then the DOS "print"
              buffers and the printer's buffers then the file
              will be deleted before it gets to the printer.
              (This is true unless you are using a more
              sophisticated "spooling" print queue utility than
              the standard DOS one.)

        "Print file"
        Passes the name of the file to the DOS "print" queue buffer.
        The second warning under "Erase" applies here in addition
        to the following...
        WARNING:  this can have unwanted side effects!
        If the DOS "print" queue buffer was not previously run
        or set up before this program was loaded then DOS sets
        up the "print" queue buffers in the memory after the
        memory this program is using.  Then when this program is
        exited DOS will not recover the program memory because the
        "print" buffers were loaded after it.  The only (normal)
        way to recover this memory is to reboot as DOS cannot
        recover fragmented memory.
           (This problem may be avoided by allocating memory
        at boot time by placing the following two lines in your
        autoexec.bat file:
            "mode LPT1:
             print/d:LPT1"
        The exact form of this may vary slightly from clone to
        clone so see the DOS "mode" and "print" commands for
        your machine.)

        "Copy file..."
        Uses the DOS "copy" command to copy the file to the 
        DOS device "lpt1" which is normally the printer.
        Use this instead of "Print" to avoid the memory buffer
        problems mentioned above.  (A possible penalty here
        is that it may tie up the machine longer while the
        file is being printed.  This depends on the file length
        and the length of the printer's hardware buffer.)


        "Open a door to DOS"
        If enough memory is available the program will be temporarily
        suspended and the user will be able to access DOS directly
        to do whatever they wish.  To get back into the program
        hit "Enter" without typing any other characters at the
        prompt.
