    Four new commands have been added to speed up redraw times
    that are not documented in the FIRST CADD manual. They are:

        (TF)  FAST TEXT -  This command allows the user to turn
                          off the text display in the drawing
                          speeding redraw by replacing text with
                          points on the display.

        (TV)  FAST VIEW -  This command allows the user to turn
                           on (display) text that has previously
                           been turned off by FAST TEXT.
                                                        
        (FA)  FAST ARCS -  This command allows the user speed up
                           the display of arcs and circles by 
                           selecting the number of points to use
                           when drawing them.

        (BA) BACKWARDS -   This command allows the user to select
                           the direction of redraw thereby allowing
                           the last objects drawn to be the first
                           objects to be redrawn.

    Current program hints and problems:

[1] CIRCLE: If and when you use the "C3" command (3-pt circle), you
    should specify on the circumference. If you should try and place
    the points in a straight line, there is no way of telling what
    you will get.

[2] Any entity that is to be stretched (ie slanted text, rescaled
    components ect.) Can not contain arcs or circles, or they will
    not appear correct. It is suggested that you use curves instead.
                        
[3] FLOPPY DISKS: If you are using floppy disks for your files double
    check that the floppy disk drive door IS CLOSED. If not the system
    will try to display an error message.
