I have been trying to learn some postscript from the Postscript Cookbook and tutorial (blue). I was trying to use the circular text example towards the end of the book. I cannot get it to go. Has any one else had this problem. I have tried on Laserwriters NTX II from Unix bsd4.3 and with atp on a Mac plus. Attached is my file I donot think that I have infringed copyright as it does not work and therefore must be different from that presented in the book. The error is not clear with nothing usually emerging from the printer. %>lpr -v -Plw file Please mail me direct as I donot usually read this news group. ----------------------------------------------------------- /outsidecircletext { circtextdict begin /radius exch def /centerangle exch def /ptsize exch def /str exch def /xradius radius ptsize 4 div add def gsave centerangle str findhalfangle add rotate str {/charcode exch def () dup 0 charcode put outsideplacechar } forall grestore end } def /insidecircletext { circtextdict begin /radius exch def /centerangle exch def /ptsize exch def /str exch def /xradius radius ptsize 3 div sub def gsave centerangle str findhalfangle sub rotate str {/charcode exch def () dup 0 charcode put insideplacechar } forall grestore end } def /circtextdict 16 dict def circtextdict begin /findhalfangle { stringwidth pop 2 div 2 xradius mul pi mul div 360 mul } def /outsideplacechar {/char exch def /halfangle char findhalfangle def gsave halfangle neg rotate radius 0 translate -90 rotate char stringwidth pop 2 div neg 0 moveto char show grestore halfangle 2 mul neg rotate } def /insideplacechar {/char exch def /halfangle char findhalfangle def gsave halfangle rotate radius 0 translate 90 rotate char stringwidth pop 2 div neg 0 moveto char show grestore halfangle 2 mul rotate } def /pi 3.1415923 def end /Times-Bold findfont 22 scalefont setfont 306 448 translate (Symphony No. 9 (The Choral Symphony)) 22 90 140 outsidecircletext /Times-Roman findfont 15 scalefont setfont (Ludwig von Beethoven) 15 90 118 outsidecircletext (The New York Philharmonic Orchestra) 15 270 118 insidecircletext showpage

It's quite simple: because the code is showed in a proportional font (which should never be done) you did read the "( )" as "()". If you know a little bit more of PostScript (I don't blame you! - the book is just for people that want to learn it) you will read it automatically as "( )" because of the statements behind it. > () dup 0 charcode put insideplacechar For example... (It appears a few times in the text, I think.) Have fun. -- -- ###### Jos Vos ###### Internet jos@idca.tds.philips.nl ###### -- ###### ###### UUCP ...!mcvax!philapd!jos ######
