There were two compile time errors to fix, and a bunch of warnings that I didn't fix. The warnings are related to pointer conversions, so I hope it does it right. I then ran it with the sample program in the Wikipedia lex article, and it ran out of buffer space. It isn't very big, either. But then I ran it with the sample from the Solaris lex man page, and it works. It even works with -r to generate ratfor output. (As far as I know, flex doens't have the -r option.) In any case, I don't understand the buffer space message. [AT&T lex was a student summer project and it has a bunch of fixed size buffers. -John]
