LetterToDigit
This is a simple function to include in a module for converting letters to digits. So if you wanted to map a name to a phone number.
For example, if you were given a phone number such as 1-800-CALL-NOW, this function would convert it to 1-800-225-5669.
Function LetterToDigit(ByVal strPhoneLetter As String) As String
Dim intDigit As Integer
intDigit = Asc(UCase$(strPhoneLetter))
If intDigit >= 65 And intDigit <= 90 Then
If intDigit = 81 Or 90 Then ' Q or Z
intDigit = intDigit - 1
End If
intDigit = (((intDigit - 65) \ 3) + 2)
LetterToDigit = intDigit
Else
LetterToDigit = strPhoneLetter
End If
End Function
