If put a comand ? and a hexa value with a letter says UNKNOWN IDENTIFIER

For example

? AA
? D0
? C1

When first is a number is well

? 0A
? 1A

ETC

If start with letter, Ollydbg assumes you mean label. When you start with number, it assumes it's hex as no label can start with a number.

So to do AA, just do ? 0AA instead.
