 Is it possible to write a DOS Critical Error Handler (INT24) for a
PC using Modula-2? If so how?

 I am using Stony Brook Professional Modula-2. I can write interrupt
routines but can't work out how to obtain the values passed in the
registers. For the Critical Error Handler these are vital as they
indicate the nature of the Critical Error.

 I don't want to have to use assembler, as the Customer Requirement
is that the complete system be written in High Level Language.
