mov ax, KeyBoardBuffer.Flags
test ax, KEY_MAKE
.if ZERO?;(ax & KEY_MAKE);CARY?what constructions possible else?

.if

.elseif

.else        ; only 1, and must be 2nd last

.endif

I mean like this ZERO?;(ax & KEY_MAKE);CARY?. I don't know about them only
.if TRUE
.if !eax
.if eax==ebx.....

        invoke GetKeyState, VK_SHIFT

ZERO?
CARRY?
OVERFLOW?
SIGN?
PARITY?

[jj2007]

The Masm developers forgot the Above? and Greater? flags, unfortunately...

[dedndave]

yes, those would have been nice
but, you can accomplish those using the "normal" conditional expressions

[Magnum]

Operator Meaning

== Equal
!= Not equal
>  Greater than
>= Greater than or equal to
<  Less than
<= Less than or equal to
&  Bit test (format: expression & bitnumber)
!  Logical NOT
&& Logical AND
|| Logical OR

CARRY? Carry bit set
OVERFLOW? Overflow bit set
PARITY? Parity bit set
SIGN? Sign bit set
ZERO? Zero bit set
