ACAD '08 user in one-man office here... Have not written much LISP code since late 80's/early 90's (still use most of it), so my "cherry" has grown back... I now have need to embellish some of my old stuff and write some new, so I obviously want to use VLIDE. Problem is, most of the lit I see around has very little plain-English info on the use of the interface. I'd like to brain up on it before I start hacking my routines. Can anybody point me to a good, comprehensive tutorial, online, printed, or otherwise? I am especially interested in the debugging tools. Thanks in advance!
