What do you mean by "branch jumps"? jmp? jcc? Something else?

And what's this DB prefixing you're talking about?

Code:

cmp eax,10
je equal10
; not equal to 10
jmp exit
[...]
equal10:
[...]
exit:

a115433,

Are you talking about branch hint prefixes? FASM allows use of segment register name as a prefix:

Code:

        cmp [Msg], WM_CREATE
     ds jne .check_wm_destroy; branch taken hint prefix

Are they useful anywhere besides Intel NetBurst (P4/Xeon)?
