I am working on a script language with bison.  I have followed the calc
examples.  what I want to know is how do you access a variable that has
already been declared inside the program that I am linking bison too? I
put in the line like in the calc4.y prog:

| VAR '=' exp        { $$ = $3; $1->value.var = $3;     }

but this only accesses the variable created during the bison session. is
there a way that I can change or have access to other variable?
