LotusScript Version of JavaScript-Unescape

On the Web, arguments are often sent in "escaped" form, to make them "Web-safe". Use this LotusScript-function to "unescape" those strings.

Function LSunescape(strIn As String) As String
' This function performs the equivalent of a JavaScript unescape
' Kenneth H?man, TJ Group AB.
Dim i As Integer
Dim strChar As String
Dim strReturn As String

i = 1
strReturn = ""

While Not (i > Len(strIn))
strChar = Mid$(strIn, i, 1)
If Not strChar = "%" Then
strReturn = strReturn & strChar
i = i + 1
strChar = "&H" & Mid$(strIn, i, 2)
strReturn = strReturn & Chr$(Val(strChar))
i = i + 1
End If
i = i + 1

LSunescape = strReturn

End Function
