Hello!
Well I've created a macro which should help to make it easier to set flags.
I have the Constants:
FLAG_C, FLAG_Z, FLAG_S, FLAG_O
and the macro
setflags macro _flags:VARARG
for flag, <_flags>
set&flag FLAG_&flag
endm
endm
and I'm calling it like this:
setflags C, Z, S, O
This should output something like this:
setc FLAG_C
setz FLAG_Z
sets FLAG_S
seto FLAG_O
but whenever i use the C for carry in the macro it translates it to this:
setb FLAG_B
which is clearly not what I want.
Does someone of you may know the reason why this is happening? and how i could fix this?
Sure i could replace the set&flag line with If-Conditions and comparing which flag i want to set and
such but i thought the current version is cooler.

setc is an ASM instuction. I would have expected an error from ML.
(setc: set if carry) ≡ (setb: set if below)
Oh this makes sense if they are equivalent!
Sorry somehow I was thinking that setb was for setting a bit but that was another instruction.
(Also I've reanalyzed my program and It's not setting the FLAG_B actually but the FLAG_C which is correct.. I was confused with the offsets since the 7th flag is actually FLAG_B and
debugging my application it said
setb byte ptr ds:[0x403007]
The weather makes me confused!)
Thanks for the help! :)
