Title: operation size not specified error?
Post by: georgelappies on April 30, 2012, 05:27:08 PM

Hi all, why when I declare a label as a word and initialize it as 0 do I still have to give the size of the label when wanting to use it?

See the code below:

Code: [Select]

label:    dw 0                        ; declare a word sized label and init it 0
               inc word [label]    ; have to put word else nasm complains?

Yes. Nasm has "amnesia" and will not "remember" that you said "label" was "dw"... unlike some other assemblers.

Best,
