I didn't know that anyone bothered writing interrupt handlers for Dos
in assembler.  One really good Dos C  book, with examples of interrupt 
handlers written in C, is the MIX programming manual, which is probably 
still under $50, including the MIX C compiler from MIX software in 
Richardson, Texas.
