.While Replacement

[FlySky]

Hey there guys,

I am having this old snippet from MASM and it uses macros like .while.

.while ecx!=_searchsize

while ecx != not equals _searchsize. How would I code something like that in GoASM?

The .while statement generates code that executes the block of statements while condition remains true.

I have no idea how to transform that for goasm.

I tried sticking in a compare like cmp ecx, [_searchsize]
je >...

but that does not seem to work.

put int 3 in front of the .While, assemble in ML or JWasm and see what Olly can tell you...

thanks MichaelW,

I debugged it and found the missing code added that to GoASM and it works like a charm now.

But isn't there any piece of code in GoASM that is a replacement for the .while macro?

Thanks for the input.

FlySky Jeremy said he's been working on adding builtin conditional statements,I was workin on a preprocessor to do it, but kinda stopped after I read his plans cause I didn't want my efforts to be for nothin. When I find out the status of that, I may finish mine up, as there's not much left to it, but yeah the way I did was just cmps/test and jmps(jne,je,etc...)

Runtime conditions are still work in progress I am afraid, but in any case they would not include "while".
