Ages ago I wrote a general purpose star routine, capable of generating the path of an n/m star (n points, each connecting to the point ±m away). In
https://github.com/jdaw1/placemat/blob/main/PostScript/placemat.ps
search for “+Star” in the routine Star, which currently spans lines 4306–4388. Star assumes the existence of DeBugLevel, but those lines are easily removed.

Parameters:
• /Left|/Center|/Right = x position relative to the current point
• /Top|/Middle|/Bottom = y position relative to the current point
• Size, in points
• /Radius|/Diameter|/Height|/Width, being the meaning of Size
• AngleOffset, being non-zero to rotate the star
• NumPoints = n
• NumStep = m
• DrawLinesInside, which if false is good for stroking.
• AntiClockwise

Example output can be seen in:

Share and enjoy.

Life is difficult because it is non-linear.
