Dear Aldweb,

I apologize for such a title... it was in frustration to several days of trying to get code to work...

In short, I have developed a simple bit of code to allow the user to draw ellipses, both hollow and filled. Here is the code...

REM location - defined by user or gathered by pen tap
C=40
D=40

S=0.01
B=0
F=PI

FOR I=0.00 TO F STEP S
X=COS(I)
X=(X*30)
Y=SIN(I)
Y=(Y*10)

V=C+X:U=D+Y
Z=C-X:W=D-Y

PSET V,U
PSET V,W
PSET Z,W
PSET Z,U
NEXT

This will draw a very fast hollow ellipse. The problem is that I would like to be able to set the

X=(X*30)
Y=(Y*10)

lines to user defined variables such as

A=30:B=10
REM perhaps gathered by pen coordinates for drawing
X=(X*A)
Y+(Y*B)

The problem is that this doesn't work for me... it only produces a straight line. Any thoughts would be most appreciated.

Again, I apologize for the *scary* title. Your math works properly, my code does not...

Regards,
bh77a
