Once I install an interrupt, how do I get rid of it?  This is because I want to write a

game.

My guiess is to overwrite the bytes you wrote on.  If you changed a 
vector pointer, then all you need to do is change it back.  If you 
overwrote the file, however, it would be smarter to either copy it 
somewhere or use the vector method.


They say one has to be good in this business.  Well I'm better.
