One last step into assembly.
Lets play with assembly language programming one last time. This time let’s use dos assembly language programming. A program is a set of instructions much like a recipe. With this recipe, we will have to use commands like you might use stir in a recipe.To make this recipe, we will use debug.com which is sort of a simple interactive assembler/disassembler. Our goal with the program is to print out the letter A. Now that seems a bit simple, but you have to start somewhere. So fire up debug from the command prompt. We are going to use dosbox (dos simulator) to make it easy to capture images. Thall shalt document. But first let us look at the letter A. If we went to an ascii (american standard code for information interchange) table we can see the letter A is 65. So far so good.. But the computer does not recognize that nunber as the letter A.
