What sadist designed it?-)  Anyway...

I suggest a simple class which holds the filedata and an index into
it.  Your functions such as GetWord(f) examine f.data from f.index
onwards, and increment f.index before returning the result.  To
"pushback", you just decrement f.index again (you may want to
keep a small stack of values - perhaps just one -- for the "undo",
again in the simple class in question).
