why sometimes the lea intr not work?

lea eax,works_
while
mov eax,works_

work very well...

thx...another question...
How to access structure members using register convieniently...
for ex:
struc test
{
.x dd 0
.y dd 0
}

and in a loop I want to do such things:

lea esi,testarray

@@:
add ,5
loop @B

but fasm don't let me do so,I din't find anyway....l to how to solve it? thx in advance...

I was also thinking how to allow you to use esi.x and esi.y labels for that purpose, and I have found a small inconsequency in my preprocessor. Then I fixed it and released still as an 1.40 (because it was really very small fix), you can download it now - you know you have the latest version when the date of release in whatsnew.txt is 28-08-2002. The thing I fixed is allowing the struc name to be recognized as symbolic constant. Because symbolic contants in every other location inside the struc macro were recognized, it was logical to allow this also with the main name.
This fix allows you to do the following trick:

struc POINT

{

 .x dd ?

 .y dd ?

}



macro assume reg,struc

 {

   virtual at reg

     local undefined

     reg equ undefined

     reg struc

     restore reg

   end virtual

 }



assume esi,POINT



mov eax,[esi.x]

mov ebx,[esi.y]

It works because of general rule that symbolic constants are replaced after processing the macroinstructions.
