Now that I have thoroughly read through an assembly book, I decided to put a simple program to the test (one that prints an exclamation mark on the screen): .MODEL SMALL .CODE MOV AH,2h MOV DL,21h INT 21h INT 20h END Now, there was a similar example in the book titled Peter Norton's Assembly Language Book for the IBM PC that went along these lines: .MODEL SMALL .CODE MOV AH,2h MOV DL,2Ah INT 21h INT 20h END I assume
