[Gambas-user] Function to count substrings

[Gianluigi]

Hi Rolf,
I do not think it exists, but it can be done by myself. :-)
As I wrote, I would do so:

Private Function CountSubString(value As String, pattern As String,
Optional compare As Integer) As Integer '' compare default Sensitive, 1 =
Insensitive

  Dim i, n As Integer

  While i <= Len(value)
    i = InStr(value, pattern, i + 1, compare)
    If i = 0 Then Break
    Inc n
  Wend
  Return n

End

Any ideas better?

Regards
Gianluigi
