IÂ´m trying to get the effective address of a label, but this instruction gives me error:

Code:

...
lea cx,label
...
label:
...

Gives this error:

lea cx,label
error: invalid operand.

Should I use offset (mov cx,offset label)? In this case gives the same error... How can I get the address of a label?

use

Code:

lea cx,[my_label]
my_label:

Remember that you can't give a name "label" - it is a reserved word.

hy peixe,

if you wanna use the offset word you can use this code
otherwise you don't need it in fasm

Code:

org 256
offset equ
mov cx,offset flat_label

int 20h
flat_label: db 'akÃ¡rmi$'
