Try the example below: \parskip=0pt Paragraph begins here\par {\letterspacefont\x=\font 0 \x THE QUICK BROWN FOX...}\par {\letterspacefont\x=\font 1 \x THE QUICK BROWN FOX...}\par {\letterspacefont\x=\font 10 \x THE QUICK BROWN FOX...}\par {\letterspacefont\x=\font 20 \x THE QUICK BROWN FOX...}\par {\letterspacefont\x=\font 30 \x THE QUICK BROWN FOX...}\par {\letterspacefont\x=\font 0 \x THE QUICK BROWN FOX...}\par \bye ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=4323&group_id=106
