How about this, which takes a character, converts it to hex, then back to a
character ...

Dim vHexNum, iInteger, vChar

vChar = "W"

iInteger = Asc(vChar)

vHexNum = "&H" & Hex(iInteger)
Response.Write ("<p>vHexNum = " & vHexNum & "</p>")

iInteger = CInt(vHexNum)
Response.Write ("<p>iInteger = " & iInteger & "</p>")

vChar = Chr(iInteger)
Response.Write ("<p>vChar = " & vChar & "</p>")

VBScript understangs things prefixed by "&H" to be hexadecimal numbers:

"You can represent hexadecimal numbers directly by preceding numbers in the
proper range with &H. For example, &H10 represents decimal 16 in hexadecimal

If all you've got is a string that you know is a hex number like "3F", just
previx it with "&H" and do a CInt (or whatever numeric conversion you want)
on it.
