A few are even working on an interpreter. (They originally targeted Clipper-compatible, which is traditionally compiled. But XBase is better as an interpreter IMO. In fact the interpreter dialects were roughly about 75 percent as fast as the compiler in my tests, and identical for some operations.)
P.S. Thanks for the confrrence tip.
