Hi all,

what is wrong with the instruction:

mov al, [cx] ; cx points to the first char of some string

I get the error: "Error: Reserved word used as symbol".

Thanks,
Marek.

In 16 bit code CX is not available as an address register.

Use [DI], [SI], [BP], or [BX]. Also [SI+BX], [SI+BP], [DI+BX], and [DI+BP].

Anything with BP always defaults to using the SS segment and the others default to DS.
