how do i enter the info in to the program. Do I use the 82h or do i enter it as 10000010

You can use binary, octal, decimal, hexadecimal ("hex") or whatever other radix (number base) your assembler supports.
Use ASCII if you like.
If your assembler supports Roman numerals, go ahead and use them!

The only requirement is that you do it in the notation supported by your assembler - you will need to read the assembler Manual to find that.

BTW: note that "0x82" is the 'C' notation for a hex number; some assemblers accept this (eg Keil), some use "82H", some use yet another representation - again, you need to check in the Manual for your particular assembler.
