English Language Version

“Program is an ordered set of instructions for the processor.” Our first program will be instructions manipulating AX and BX in plain English.

move 5 to ax
move 10 to bx
add bx to ax
move 15 to bx
add bx to ax

Even in this simple reflection of thoughts in English, there are some key things to observe. One is the concept of destination as every instruction has a “to destination” part and there is a source before it as well. For example the second line has a constant 10 as its source and the register BX as its destination. The key point in giving the first program in English is to convey that the concepts of assembly language are simple but fine. Try to understand them considering that all above is everyday English that you know very well and every concept will eventually be applicable to assembly language.
