Just one note: this comment:
HOLDTKNBUF := Null_unbounded_string; -- looks like Ada automatically
init's all declarations to either 0 or null, as suits the data type
is wrong. Integers are not initialized to anything and cannot be counted on; same for floats, booleans, other enumeration types, etc. Access types *are* initialized to null by default, though, and the language specifically requires that Unbounded_String types be initialized by default. It's possible that everything could get initialized to 0 in a particular implementation, though, either because the compiler vendors decided to make the code do that, or the OS does that when loading the program, or often just by luck.
