Does MOV AL test if al is even or odd?

mov al
101b test al

100b doesn't test if AL is even or odd. Maybe you mean mov al
101b test al
001b where the lowest bit is tested. related:Assembly check if number is even explains why test al

Just add 2 to SI at the end of each iteration - no need to move the elements around. Note that it should be 2
Not 1
Since you're dealing with words. AlsoThere's no need for DIV. You can check whether a number is odd or even by testing the least significant bit using the TEST instruction.

Nice idea for a short 8086 program. However, it has a few flaws: 1. It expects only one ASCII character, so technically user can input only numbers from '0' (ASCII `0x30`) to '9' (ASCII `0x39`). However, there is no check whether user pressed a number key, or any other key - only `0x30` is subtracted from `AL` after the `INT 0x21` call.
