In an Intel 8088 processor-based system, such as the IBM Personal Computer, adding new hardware to the system may necessitate providing an interrupt handler to service hardware interrupts associated with the device, or a user may wish to handle existing device interrupts in a different way. The present invention is a method that addresses both of these concerns. The invention is an assembler language program that allows coding of a personalized system interrupt handler in Pascal or a similar high level language. In prior-art systems such interrupt handler programs are written entirely in assembler code. The use of the present invention allows the routines to be programmed in a high level language and therefore to be readable, easily understood, more maintainable, and easier to modify.
