You are correct about adding .data not being quite enough (there also 
needs to be a corresponding lock call and determine the size of each
locked section properly) - but not the reason with the DS alias.
We have a flat address space so CS = DS (as far as base address)
So the sections only matter to the linker as far as where it puts
the variables/code.
