============================================================================
>>>  PREFERENCE
    If you are going to make a session file, please be sure that you fully
    understand this sheet, and how a session operates. If your code
    does not work at first, you've might've forgotten something. If you've
    THOROUGHLY sifted through your code, and still can't find out the
    problem, please notify me, and send me a copy of your code.

>>>  THE COMMANDS
    The first description line provides a short explanation of the function,
    the second provides the parameters, including the calling symbol, and
    possibly a couple of numeric commands (such as -1 to remain unchanged.)
    Use of non-numeric characters, are preferred to be placed inside of
    "quotes", but this is optional in certain places; see FORMAT13.TXT for
    details...
