as long as there isn't ( expr ) in the input input move up without

However once input does have an ( expr) part, $<blIdentifier>1 at

level has the value of $<blIdentifier>1 at the ASSIGNMENT level.
When I add
the following action to the ( expr ) production-
{strcpy($<blIdentifier>1,
$<blIdentifier>2);}, $<blIdentifier>1 at the ADDOP level has the
correct
value but then the $<blIdentifier>1 at the ASSIGNMENT level value is
what I
changed $<blIdentifier>1 to be at the ( expr ) level. I'm very
confused.
If you do not write out an action, { $$ = $1; } will be added
implicitly. SO if you have something special that must be done, it
must be written out explicitly.
