I've heard that some commercial yacc-alikes include a dBase grammar... (yeah, I know, that wasn't what you were asking). As a trivial aside, I'm not convinced that the real dBase language (in all its glory) is close enough to context free to be yacc'ed. Of course, practical and usable subsets could be easily implemented. And I might well be wrong, since I've used the language a lot but never studied it.

Uh-oh, watch out. Aston-Tate seriously attempts to convince the world that they own the dBase *language*. They claim that you cannot implement this language without their permission (they have sued the FoxBase folks) and I would not be surprised at all to learn that these guys are mad enough to believe that their copyright or patent or whatever extends to the grammar of the language. Better stay away from anything that look even remotely related to Aston-Tate or dBase. /Lars -- Lars Fischer, fischer@iesd.auc.dk | It takes an uncommon mind to think of CS Dept., Univ. of Aalborg, DENMARK. | these things. -- Calvin
