— The second token value or zero if the first token is a primary tag.
Outputs:
A pointer to the catalog string associated with the token specified by the
input values. The return value may be a NULL pointer if no string is
associated with the input values.
Assumptions:

any type of arbitrary constant (@1, @n1, etc.). These types will cause the
routine to return a pointer to the string “_ERROR_”.
