I'm not sure if you are aware that you first have to install an interrupt handler in vector 3 before executing INT 3. The debugging mechanism (such as DEBUG does) is to replace the next instruction to be executed by an INT 3, just before executing the program, and then swap it back to the previous opcode. g123,234,345 installs INT3s in 234 and 345 (temporarily) But before that, DEBUG installs a pointer at the vector location pointing to a routine which knows how to handle it. You should too, in you tiny assembler program. If, using TP 7, and using F7, you have a crash, then look at the code you are executing. It's unlikely to be DOSEMU's fault. I've used F7 many times.
