Hello everyone,
I need to check whether a command exists.
Let me explain: I made an application compatible with AutoCAD and BricsCAD.
Unfortunately, some commands are not available in all applications cad, so I would like, through lisp code, check whether a given command exists.

eg.

(check "LINE") -->T
(chech "TRTRTR" --> nil

How can I do this?

I have been searching a way to determine whether a .NET function is loaded.

Some things might be so easy!

Thanks for the hint.
