Declaration of variable in bits

[Sandro.BR]

Hey Mr. I am beginner in MASM, would like to some help,to use in Windows. As it is declared a variable with the size defined in bits, as well as is fact in the C (int var:3;) ? I ask one more gracefulness,  don't use abbreviations or jargons, because I am going to translate for my language (português.brasil). Thank you very much.

Hello,
use RECORD for 8,16 or 32 bits variables. EXAMPLE RECORD Quatro:4,uno:1,tres:3
4+1+3 = 8 = 1 byte
.data
mot EXAMPLE
.code
mov mot,al
and mot, MASK uno        ;   MASK uno =00001000b
