Hi Francesco, If you change it to:- .pdfhref W -D \\$[1] -- "\Z'\\$[2]'\v'0.25m'\D'l \w'\\$[2]'u 0'\v'-.25m'" You won't see the error. In the next version of groff this is not necessary, you don't need the "--". You can get groff to draw a border around clickable links, not quite the same as underlining. ============================================================================== Hotspots can have a border drawn around them, which is controlled by setting the register PDFHREF.BORDER to an array of 3 numbers which represent – horizontal corner radius, vertical corner radius, and border width. A zero radius gives square (not rounded) corners. The default is:- .ds PDFHREF.BORDER 0 0 0 Which produces no border around the hotspot. ============================================================================== Cheers Deri
