 		 #150905 - the infamous intel notation of hexadecimal numbers
Responding to: ???'s previous message
... requires numbers starting with non-numerical characters ('A' to 'F') to be prepended by a zero.

Otherwise, the assembler thinks you are trying to use a symbol (label, variable name etc.) "DD", which you clearly don't have (if you would, it would not complain, but it would yield a nonsense program).

The correct notation for your case is, then:

MOV TMOD,#0DDh
