A few replies.

1)  For those of you looking for the Fractals:  I will post the one
    (lone) fractal picture on Apple2-L as soon as I get Executioner
    from the LISTSERV.  I can post the program, which is in BASIC, but it
    requires a super-res Ampersand routine from Nibble, and is SLOW, SLOW,
    SLOW...it took 14 hours to do a regular magnification Mandelbrot set
    (it would probably take over a day to do any higher magnification).
    Please send replies as to the feasablilty of sending this program.

2)  Someone wanted to know about the status of the VT220 GS emulator...due
    to my status as a full-time student, I have not yet completed the
    control-sequence coding.  all ESCape coding is finished, as is all
    graphics programming.  Expect this program to be posted on Apple2-L
    within a month (I hope...)

3)  I have actually saved the fractal as a screen-format picture (can be
    loaded by Paintworks, DeluxePaint, Display.Pic, etc.)

4)  Re:  Paintworks Gold...I have to purchase the magazine which I found
    the address in, and will post the info when I get it.

5)  Re:  What's a fractal?   Good question.  It is a non-linear function,
    which depends on previously obtained values.  The general formula is
    x    = f(x ) + c
     k+1      k

    The value of x is obtained from previous values of x.
    these functions range from the Mandelbrot set (a complex-numbered set
    whose formula is x = x * x + c) to random-displacement fractal
    mountains.
