I like it.  Thanks!

Dear Ziggy,

there is another nice way to do the same -- try

\rput(0,0.5){\psline(0,0)(0.25;45)}

Now if you separate coordinates with a ";" instead of a "," -- this tells PSTricks to use POLAR COORDINATES (Radius;Angle with positive x-axis) instead of (x,y)

Very helpful for lines with a given length and angle with the horizontal starting in the origin.

Just as a little addition.

Regards,

Jürgen

Juergen:
I can't believe I made as stupid a mistake as that and didn't catch it.  Thanks, this seems to work fine.

Dear Ziggy,

what about:

\rput{45}(0,0.5){\psline(0,0)(0.25,0)}

In the "(...)" PSTricks wants the coordinates -- seperated by a COMMA...

Hope this helps.

Regards,

Jürgen

If I want to draw a vector of length, say, 0.25 making an angle of, say 45 degrees with the horizontal, and put it so its tail is at, say, (0,0.5), what is wrong with writing
\rput{45}(0.05){\psline(0,0)(0.25,0)}
?
I am getting the error message
./Parallel.tex:477: Missing number, treated as zero.
<to be read again>
                   \relax
l.477 \rput{45}(0.05){\psline(0,0)(0.25,0)}

If I hit "r" (ignore) the vector prints properly, but I would like to know what the missing number is.
