I´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:

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 'akármi$'
