I have a very simple question, and need an answer.  Is it possible
to write an interrupt handler for one of the Int 21 interrupts
(in this case, File Open and File Write), such that things
can be made re-entrant?  In other words, can I write the handler
so that it can call a random Pascal unit that may do all kinds
of unknown things?  And if so, how would I go about doing this?

Thanks in advance for any help.
