Code:

a equ 12
b equ 12 + x
if a relativeto x
  display 'Hi'
end if

If x is not defined, it says

Error: symbol 'x' is undefined or out of scope.

Code:

a equ 12 * x
b equ 12 + x
x=0
if a relativeto x
  display 'Hi'
end if

If x is defined, it displays, regardless of whether x-a is a constant.

This works the same as in fasm - if you assemble the above samples with fasm 1.71, you're going to get the same results.

The only difference is that in fasm "relativeto" can only be used to check if expression is relative to one of the addressing symbols pre-defined by the assembler (like "if a relativeto ebx"), while in fasmg you freely define such symbols yourself, with "element" directive:

Code:

element x
a equ 12
b equ 12 + x 

if a relativeto x
  display 'a'
end if

if b relativeto x
  display 'b'
end if
