I have big data (2000 lines)
I show for example this(small part):

Code:
B0000001

A0000220

C00AB222
    


I need macro, this macro must create this:
Code:
dd 0xB0000001

dd 0xA0000220

dd 0xC00AB222

[Normally I'd use an editor/script to prepend dd 0x to the first line and replace newlines with ",\<newline>0x"; then just assemble as normal.]

In FASM the basic outline would be:
Code:
virtual at 0
input::
        file 'test.txt' ; list of 32bit ASCII hex
        len = $
end virtual

repeat (len / (8+1+1)) ; 8 hex CR LF

        db 'db 0x'
        load q qword from input:+(10*(%-1))
        dq q
        db 0x0D,0x0A

end repeat
                            
Note I've assumed windows line endings, you can add in detection etc for this.
