VLISP vs VBA

[scwegner]

Depends. Each one has it's advantages and disadvantage (http://www.afralisp.com/vba/api.htm)s. Oh, and don't forget ObjectArx.

ObjectARX is going to be harder to learn than either VLISP or VBA because you must know C++ to be able to program in it. ;)

However, I do agree that the other two have their own advantages and disadavantages. It really depends on what you need to do. Also, learning one will help with learning the other as they both use the object model. :D

Personally, I started with VLISP before trying to go to VBA. But, you could easily go the other way. When learning either of them, VBA has an autocomplete feature while VLISP does not. By using the autocomplete, you can learn what commands and properties are associated with each object. However, you can do the same by looking in the help files. ;)
