>[how do I call a bison yyparse() more than once?]


I received several answers to my previous posting.
Thanks to you!


To summarize, there was actually two things to do.


1. Call bison's cleanup routine
yyrestart(yyin);


2. Use flex cleanup facility. Add to the action part of a flex specification:


<<EOF>> {YY_NEW_FILE; yyterminate();}


Regards from
Hans:-)
