Fasmw 1.73
Situation. Macro check a, b {...}
My Macro must show equal if a = eax and b =[eax]
Because the same register.
How do this?
Using eq or eqtype ?
Or another way, how apply a [] and get a=[eax] and b=[eax]?
Or do match for b and cut [] and get b=eax

And how separate alphabet chars and symbols like [,], *, {,}, &?

Or if a eq eax then aeq equ 1
If b eq [eax] then beq equ 1
If aeq=beq then a and b equal.

Code:

macro t a, b
{   match =[x=], b
    \{  if a eq x
            display "1"
        else
            display "2"
        end if
    \}
}

t eax, [eax]
t eax, [ecx]

eq works fine also.

Code:

macro tst a, b {
        if [a] eq b
                display `a,13,10
        end if
}
tst eax,[eax]
tst ebx,[eax]
tst bx,[bx]
