If you are referring to variables defined in function scope, the answer is:-
you need an AST for the language. In the simplest of cases, you would have a
linked list with variabkes defined in a function hanging from the
corresponding nodes. this way variables with same names in different
functions can be distinguished. if the langauge permits recursion/nested
calls, you would use a tree of stacks as the data structure eg: pascal/C.
