this will give you the binary string equivalent of every asc number (0-255) using the And function
(both have to be the same to give a 1
example:
10010101
00101001 and
=01000011 )

For k = 0 To 255
Temp = ""

For j = 7 To 0 Step -1

If k And (2 ^ j) Then
Temp = Temp & "1"
Else
Temp = Temp & "0"
End If

Next j

RL88(k) = Temp

Next k
