Thread: referencing C structure elements in assembly

I tried moving to general purpose register, even that gives problem..

And size is proper, It is unsigned short which is 16 bit. When It is word(32bit) compiler shouts.

My statement is like this
mov ax, state[state_ptr].stack_segment
.. and when I compile using VC 6.0. the error is

error: C2424 : '[' : improper operation in second operand

please advise..
Thanks..
