I am trying to create a function that strips a MB string of the Chinese characters or any non-alphanumeric characters in a string. How can I best achieved this? I am trying to use the following function str.containsMBchar but it doesn't seem to work? Any work around with what I need to achieve?

Syntax:
function boolean str.containsMBchar (const string string$)

Description

Return values

false in any other case

Context
This function is implemented in the 4GL Tools and can be used in all script types. This function is available from TIV level 1700.

could you share the code please?

No idea in baan but i did something similar in Excel.

User defined function for Excel to count number of non-ascii characters in a cell
In Excel
1. Press <Alt> + <F11> to open VBA editor
2. Insert new module
3. Paste following text
Function bt_255(s As String) As Long
Dim j As Long, iCode As Integer

For j = 1 To Len(s)
iCode = AscW(Mid(s, j, 1))
If iCode < 0 Or iCode > 255 Then bt_255 = bt_255 + 1
Next j
End Function
4. To use in Excel workbook enter as formula “=bt_255(A1)”

Can you elaborate your requirement?

You can use mb.export$() and mb.import$() functions to handle MB strings.
