[comp.sys.handhelds] Casio fx-8000G Mandelbrot problem

gchow@undergrad.cs.ubc.ca (george kai yee chow) (04/15/90)

Since this is a handheld area, I thought I might try my problem here.
I've got a Casio fx-8000G and wrote a Mandelbrot plotter. (How's the one for
the HP-28s.)
But there's a problem with it: it only plots one point in the set.
I'm posting the source here. If anyone can find the problem with it, can 
they please e-mail me? (I would love to hear from anyone with a Casio too.)

Note on notation:  -> is the assignment operator
                   ^2 is the square operator
                   => is the conditional separator (shift-7)
                   >= is the greater than or equal to symbol
