Why not try to shorten the if statement by creating a variable for Mid(strSTRING,iPos,1), like thisChar = Mid(strSTRING,iPos,1). Then you replace all instances of the mid with "thisChar" (or whatever name you choose). This would shorten your code (typing) and not have it calcualting the equation 10 times (even though it's in the buffer).
