osht. If anyone remembers my old thread I was looking into directly setting flags... >___>;

Code:
STC - Set Carry

        Usage:  STC
        Modifies flags: CF

        Sets the Carry Flag to 1.

                                 Clocks                 Size
        Operands         808x  286   386   486          Bytes

        none              2     2     2     2             1


Ahem.
But anyone know why this only exists for the Carry Flag, Direction Flag, and Interrupt Flag?

There's also this:
Code:
SETE/SETZ - Set if Equal / Set if Zero (386+)

        Usage:  SETE    dest
                SETZ    dest
        Modifies flags: none

        Sets the byte in the operand to 1 if the Zero Flag is set,
        otherwise sets the operand to 0.

                                 Clocks                 Size
        Operands         808x  286   386   486          Bytes

        reg8              -     -     4     3             3
        mem8              -     -     5     4             3

That kind of thing, but there's no unconditional SET operation!

You could do it the cheap way, like;
Code:
STC //set carry flag
SETC dest //set destination if CF = 1 (which it is now)


(I do know that SETZ/C are only for specific processors.)

Yes, I know. That was one previous theory. Another was using SAHF/LAHF (which nog_lorp) perfected.
