Hi, all For those of us who are working on the parser, and compiler, 'A Guide to Lex & Yacc' by Thomas Niemann should probably be prescribed reading (if you haven't already read it). This is a really constructive guide to using the two together, and very informative. However, the most interesting part that I noticed is on the second page, under the 'Other Titles' section. It's called 'Operator-Precedence Parsing'. I haven't yet managed to get to it, because the web server (or my browser, I'm not sure yet) keeps hooching over the page, however, I'll put money on the fact that it will provide us with some insight into solving the current operator problem(s?) that we have (see previous postings titled 'Status Report: long query string changes' and "Postgres' lexer"). I will try to get it. If anybody wants a copy and is too lazy to go to the web site, let me know and I'll mail you a copy. MikeA
