Don – Hi! Long time-no type. Yes, many AutoLISP functions could be passed thru a black-box, and come out the other side as C functions. But, keep in mind that AutoLISP functions do not contain declarations, and symbols can reference values outside of the body of the function they appear in. In C, you can decalre a symbol as a global, but you can't reference a variable bound to another environment, dynamically, which is what they refer to as 'dynamic scoping'. There are probably many functions that will convert, some easily, and some not so easily, but I'd really love to see someone illustrate how to convert any AutoLISP program that does something like this: (eval (read "(some-function some-argument)")) You can do it, all you need is to bind a LISP interpreter to your ADS program. <g> -TonyT.
