I don't get it...

Let's suppose "dat:" is at 9da0h (just for the sake of example...)

ld dat,a would translate to ld $9DA0,a
this would be an attempt to load the value of register "a" into a numeric 
constant ($9DA0) quite impossible. An instructioon like that isn't even
in tasm80.tab (ld *,a doesn't exist)

ld (dat),a woult translate to ld ($9DA0),a
this would load the value of register a into the memory location with 
address $9DA0 (or "dat") that's what you want to do.... so i'd definately
use ld (dat),a
