I'm applying a method ....mthd> *Obj to each line of a file in turn. I've tracked a problem down to when that method operates on line 3738 but am unsure of exactly how to trace the method from that point on. I see that trace operates in debug mode but again am not exactly sure how to ensure that I am in debug mode on a method (rather than a function which is just (debug 'Fn) at that point. I have tried but get can't trace. Any help much appreciated.
