I am in need of a DOS version of lex and yacc. Is there anything available commercially or in the public domain (especially via anon ftp)? Please respond via email. I'll forward to any other interested parties (better send me email if you're an interested party). Patrick Heck University of Virginia plh@cs.virginia.EDU Computer Science Department

Try the following: wuarchive.wustl.edu:/mirrors/msdos/txtutl/bison111.zip wuarchive.wustl.edu:/mirrors/msdos/txtutl/byacc.zip wuarchive.wustl.edu:/mirrors/msdos/txtutl/flex23.zip Bison is the Free Software Foundation's YACC replacement. It carries some licensing strings that may or may not be desirable in your project. BYACC is a port of Berkeley YACC, a completely public-domain yacc developed at Berkeley. I did an early port of this and found it to be quite useful. There are no licensing strings attached. Flex is "Fast Lex", developed at Berkeley and elsewhere. This has been adopted by the Free Software Foundation, but I believe that it carries a Berkeley-style "Do what you want, but don't hold us liable" copyright. Its output code is in the public domain -- no strings attached. I think you will find any of these tools to be stable enough for real-world programming. They are also substantially cheaper than MKS's commercial equivalents. (In other words, they're free.) Maybe this question should go in the Frequently Asked Questions list. I see it every month or two, and the usual response does not mention the free alternatives to the commercial lexes and yaccs. -- Stephen Trier "So don't expect replies for a day or two Case Western Reserve University (until the computing centre staff gets back Information Network Services from wherever they hide on weekends. ;-) )" trier@ins.cwru.edu - cplma@marlin.jcu.edu.au

For anonymous ftp try msdos.archive.umich.edu Look in msdos/programming/util there we have flex.zip (fast lex) bison110.zip (GNU Yacc) byacc.zoo (Brigham ver) tcbison.arc (TC version) All of these come with source, and tcbison also has lex source. As to Austin Code Works, going by their price list in this months C Users Journal, for the same byacc and flex that we have for free they charge byacc $35 flex $25 Any questions about the Univeristy of Michigan MSDos archives should be directed to PC1_Organizers@um.cc.umich.edu, mail about the archives sent anywhere else will be sent to /dev/null. --Allan
