Hi,

Is it possible to use a macro (or similar construction) inside an instruction? For example, imagine that I want to create a special value from a given integer. Example:

Code:
MOV EAX, MAKE_SPECIAL_INT(0x1000)
    


I have created something like:

Code:
macro MAKE_SPECIAL_INT value
{
    0xFFFF0000 + value
}
    


But FASM says "extra caracters on line". Is there any workaround to accomplish that?

Thanks!

fasm doesn't support inline macros. You will need to override the MOV instruction and detect the special values inside that.
