|I'm not familiar with anything that could tell you what file is at that address. BASIC had PEEK and POKE commands where you could peek at an address and see what was there or poke an instruction into the address but I don't think it'll tell you what file is there and I don't know if there's anything like that for dos.|
If all the program's files are in the same directory maybe you could figure it out using the file date, time or name.
