The program Visual Comparer works really well for viewing and editing 2 similar files. You can see the differences and update one from the other. I recently contacted them about making a color parser for Vlisp, since their parser is compiled to a .dll rather than readable. They asked for a list of elements so I sent along Michael Puckett's exhaustive list for TextPad. Now they are requesting a representative .lsp file to test with. Does anyone have a largish program that includes a variety of commands, symbols, operators, etc? It can be specialized; I don't intend to run it, just pass it along. If so please reply first before posting the routine so the server doesn't get swamped. Thanks, rs
