This function recursively follows variable references and returns the original variable that was referenced by the original variable.
A reference variable is a special variable that does not hold value itself but rather a pointer to another variable. Such reference variables are used when arguments are passed by reference to BASIC subroutines.
Calling this function the caller can get the original variable and the
valéue of the original variable rather than a reference.
