is not obvious for everybody.

being curious, i tried your program with the same results... then i changed the

I was going to comment that the 'bitmask example doesn't work, which it
didn’t, but looks like its been recently fixed by adding the needed
QWord cast on the '1's.

Qwords are certainly trickier to use the Dwords.

Hi All,

uses sysutils;

mask1, mask2: QWord;
begin
mask1 := $ shr 24;
WriteLn(IntToHex(mask1, 16));
res := 24;
mask2 := $ shr res;
