do - define oword
an oword is an 8-byte data type.

Code: [Select]

SECTION .data
blah do 0
is the same as

Code: [Select]

SECTION .data
blah db 0,0,0,0,0,0,0,0

i know..
but, NASM Manual said:  DT, DO and DY do not accept numeric constantsas operands.

and nasm occur error:

error: integer suppild to a DT, DO or DY instruction

AND the question:
DT, DO, DY  -- how to use?

[mik]

thinks

and  DY ?

[Keith Kanios]

and  DY ?

I would imagine the same, except being 256-bit for the YMM registers... where-as DO is 128-bit.
