### Syntax:

    InStr ([Start As Long,] String1 As String, String2 As String[, Compare]) As Integer

### Return value:

### Parameters:

Start: A numeric expression that marks the position in a string where the search for the specified substring starts. If you omit this parameter, the search starts at the first character of the string. The minimum allowed value is 1. The maximum allowed value is 2,147,483,648.

String1: The string expression that you want to search.
