PERSONAL OPINION :
Anyone learning lisp, Vlisp may be better served using the VLIDE from Autocad, to take advantage of ;
Integrated Help,
Integrated formatting,
Integrated debugging < this is a biggie >
Integrated Intellisense < for want of a better expression >
Appropos,
In line evaluation.
etc, etc, etc.
I believe that a lot of questions I see on forums could be resolved by use of the VLIDE.
Note : I have read arguments that using any integrated editor is evil .. and I don't want to get involved in that discussion here.
