this is my source. i'm beginner but i did my best to think about and
make it.
i can get the exe file but this exe file doesn't change hex to
decimal.
what i try was after get the input by the keyboard, assign through the
indirect address and multifly each digit with power of 16 and sum up.
but the result was nothing i mean even thogh i got the exe file, it
didn't work
please save from this chaos.........

hexdec1 segment
ASSUME CS : hexdec1,ds:data

mov ah,02h

Well, I've got good news, and I've got bad news:

The good news:

It's much easier than you've shown. All you need is a CVD instruction.
(Convert To Decimal).

The Bad News:

You'll need to change platforms, or find the correct/appropriate
group. <g>
