I thought the operator ~ was a conditional assembly operator. Turned out it evaluates correctly at compile time as well. Or am I interpreting this wrong altogether? Not very good at this.

Code:

.if ~ebx  ;.if ebx = 0
    mov ax,0x30
    stosw
    stdcall prnstrz,addr valstr
    ret
.endif

For the native if ~ means a logical not. For the macro .if ~ can mean anything the macro author desires.
