How to convert between ASCII and EBCDIC character codes

Function Translate(ByVal InText As String, xlatTable As String) As String
'
' Uses a translation table to map InText from one character set to another.
'
Dim Temp As String, I As Long  Temp = Space$(Len(InText))
  For I = 1 To Len(InText)
    Mid$(Temp, I, 1) = Mid$(xlatTable, Asc(Mid$(InText, I, 1)) + 1, 1)  Next I
  Translate = Temp
End Function

Function ASCII_To_EBCDIC_Table() As String
'
