I'm told my recent posting requesting PostScript for drawing perpendicular
lines to a circle was confusing and ambiguous. Let me clarify.
I would like to draw a circle, and lines which are perpendicular to lines
tangent to the circle (much like the lines on a clock face). I would
also like to print text whose base line is parallel to the tangent lines.
Thank you.

I would >also like to print text whose base line is parallel to the tangent lines. Here is some untested code. Let cx, cy be the center of the circle. Let r be its radius Let theta be the angle around the circle at which you'd like to draw one of your radial lines or print text tangent to the circle % Align X axis with circle cx cy translate theta rotate % Move to perimeter of circle r 0 translate % Draw the line where you want it -10 0 moveto 0 0 lineto stroke % Rotate to put text tangent to the circle % (if you speak hebrew, negate the angle!) -90 rotate (This text is tangent) show
