Lets say I make two marks, called mark1 and mark2. Now I want to make two other marks: mark0 and mark3. mark0=mark1-(mark2-mark1) mark3=mark2+(mark2-mark1) I'm trying to look at the marks.scm code, but I'm really stuck;). Are there more code examples of using marks?. Any pointers how to proceed?. -- Esben Stien is b0ef@e s a http://www. s t n m irc://irc. b - i . e/%23contact sip:b0ef@ e e jid:b0ef@ n n
