This is not really all that DJGPP-specific, but...



Your yyparse() automatically looks for a yylex() function. So all you need
to do is call yyparse(); and make sure your yylex() looks in the right
place for what it is to parse.

As for modifying variables, the code that ends up in the parser can fiddle
global variables, but it can't access class member variables as yyparse()
is just a global function. (You could, I suppose, generaye a yyparse() and
then modify the stuff Bison output to make it Foo::yyparse() though.)
