Sure, assembler is not C. ;-)

You'd need to compute the address yourself in assembler.

lds is probably the wrong operation to try.  If you want
the compiler to do the address calculation on your behalf,
rather let it pass you the fetched value in a register.

p.s.: This is supposed to be a closed list, so without a
subscription, you risk missing answers.
