a simple question, what does ubound in this code means?
VB Code:
  1. Dim folding() As String

  2.  
  3. folding() = Split(txtFolding.Text, "+")

  4.  
  5. If UBound(folding) = 1 Then

  6.                 result = result + Val(Mid(txtNumber(i).Text, Left(folding(1), 1), Len(folding(1))))

thanks
