- I have my favorite PD editor which I use for small - quick little progs.
- I decided that I would go in with Dos debug and just change the color attr
- byte - so I can see my screen better - guess what?
- The program knew that I modified one byte! and gave me an error message
- accordingly! "Program has been altered" and blew up!
-
- This is my question because now I am curious - does anyone know of TP prot
- schemes along these lines or is this a strictly assembly thing?
- How can a program do this!!!????
