Debugging is associated with a name. So, for example:
exampleadv=:1 :0 exampleverb=: u/ 13!:3'exampleverb *' exampleverb ) (Experimentation showed me that I had to set the stops after I created the definition, for this to work.) 13!:0]1 +exampleadv 1 2 3 |stop: exampleverb That said, note that you cannot step through lines within the verb unless its top level is an explicit definition.
