Retrieves the most significant word of a long variable.
var = HIGHW( s )
The variable that is assigned with the MS word of var S.
The source variable to get the MSB from.
There is no LowW() function. This because when you assign a Long to a word or integer, only the lower part is assigned. For this reason you do not need a Loww() function. W=L will do the same.
Dim X As Word , L As Long
L = &H12345678
X = Highw(l)
