Code:
worldedit.exe+1C1430 - 0F95 C0               - setnc al



The Opcode (0F95) actually implies setne, as setnc would be 0f93, still it displays setnc. The Little description bar below shows "set byte if not carry (not equal)", which is even weirder, as equal usually means zero, not carry. I remember coming over such an instruction and didn't understand why it was triggering already (i think i even asked it as a question here), and this would actually explain that behavior. Possibly a bug?

Newest CE (CE6.3Beta2) has this:

0F95 C0 - setne al
0F93 C0 - setae al

note, CE treats "setnc al" as "setae al"


So, is it still wrong?

setae would be correct i think. Above or Equal would be not below, which means x-y gives an overflow and sets the carry flag, so
AE -> NB -> NC.
Nice to hear that it's fixed for 2.3 already Smile
