O'REILLY PUBLISHES COMPLETELY REVISED GUIDE TO LEX AND YACC 

SEBASTOPOL, CA -- O'Reilly & Associates announces the release of a 
completely revised guide to two important UNIX programming tools,  lex and
yacc.  For the second edition of LEX & YACC, authors Tony  Mason and Doug
Brown are joined by John Levine, moderator of the  comp.compilers
newsgroup on the Internet.  Nearly twice the size  of the original, the
second edition contains new and revised tutorial  and reference sections. 
The new materials should provide more help  for new users in learning lex
and yacc  as well as for seasoned  programmers who need to understand some
of the complexities of these  programming tools.

When LEX & YACC was first published in May 1990, CommUNIXations  magazine
noted that it covered topics, "usually left out of introductory  and
intermediate UNIX or C courses but [which] can enhance the  productivity
of any programmer who needs to talk to CRT screens or write  applications
programs that are user friendly." In the new edition, the  authors have
provided new, extended examples that show the variety of  applications for
lex and yacc.

Major changes include:
 
*  Lex and yacc each have a chapter devoted to understanding 
   basic usage and simple, stand-alone applications;
*  A new chapter with full SQL grammar; 
*  Greatly expanded reference chapters;
*  Coverage of the new POSIX 1003.2 standard versions of lex 
   and yacc;
*  Full coverage of all major MS-DOS and UNIX versions of lex 
   and yacc, including AT&T lex and yacc, Berkeley yacc, 
   Berkeley/Gnu flex, Gnu bison, MKS Lex and Yacc, and Abraxas 
   PCYACC.

LEX & YACC, 2nd edition, continues to be the only book exclusively devoted
to these two important UNIX programming tools.  Every chapter from the
first edition has been wholly revised, with new, expanded examples
replacing old ones.
