Example

The following example examines the value of the profit variable. If this value is a negative number, then it displays 0 for profit:

Sub Button_Click
      Dim profit as Single
      Dim expenses
      Dim sales
      expenses = 100000
      sales = 200000
      profit = Val(sales)-Val(expenses)
      If Sgn(profit) = 1 then
         'Yeah! We turned a profit!
      ElseIf Sgn(profit) = 0 then
         'Okay. We broke even.
      Else
         'Uh, oh. We lost money.
         End If
