Is this part of a larger program? What is the entry point? It looks like it's designed to start at 11b. Are you telling the debugger to start running your program at 11b?

Also, I don't see where the program exits back to DOS. From what little I've Googled on the subject, here's how you're supposed to exit to DOS:

Code:
mov ah,4ch
int 21h

In other words, you can't just "ret" back to DOS (if that's what you're trying to do at 138).

I don't do DOS assembly programming (talk about pain!), so I probably can't give you much more help than that.
