I have a problem with opx's too:

One of my first progs=simple:

random
op1toop4
random
op1toop3
random
op1toop2
random
cline    (draws line from (OP1,OP2)-(OP3,OP4))

The output of this program is very strange

My window size needs to be:
(xmin,ymin)-(xmax,ymax):
(0,0)-(1,4100) !!!
This is very strange and:
one coordinate has always x=0 and the other coordinate has always
y=0!

Please reply,

Wouter

Do you know why W'98 crashes ALMOST everytime?
It is written this way:
If randomizer<0.99 then Crash
