accessing yyval outside lex and yacc

[Manju James]

Hi - i am a realtively new user of Flex and Bison -

was wondering if sumone could clear a doubt for me.

Is it possible to access yyval externally (from another file -  for
instance)?
I would like to gain access to the $$ value of the  last
non-terminal/terminal that yyparse() builds.

I am calling yyparse() from main() in a separate C++ file - and it seems to
work fine - and now i want to use what it builds.

would be eternally grateful for any help received.
