    Wouter:

    No, you can't keep the LIST line from printing, although this
    feature has already been requested and is in Microchip's
    "requested MPASM features" database.

    The easiest way to keep the table from filling up with lots of
    temporary variables is, obviously, to use as few temporary
    variables as possible.

    MPASM makes this easy with the "SET" directive; SET works just
    like EQU, except that it allows its asociated symbol to be
    re-assigned a new value later in your source code.

    For example, this code won't work:

        TEMP    EQU     1       ;TEMP = 1 from this point forward.
        ....
        TEMP    EQU     2       ;This line causes an error; variables
                                ;defined with EQU can't be redefined.

    but this code will:

        TEMP    SET     1       ;TEMP = 1 from this point forward.
        ....
        TEMP    SET     2       ;This line works; TEMP = 2 from this
                                ;point forward.
        ....
        TEMP    SET     3       ;Now TEMP = 3.

        etc....
