The '%' character is used to mark the start of comments in Postscript.  Thus if your
lines all begin with '%PS', then they will all be treated as comments and have no
effect.

If you remove the %PS then there are various other errors within your code
fragment. Ghostview has a display window that shows the error messages.

The basic reference for the Postscript language is the 'Postscript Language
Reference Manual 3rd Edition' as known as PLRM 3rd.
