## Skilagildi:

## Viðföng:

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 maximum allowed value is 65535.

Text1: The string expression that you want to search.

Text2: The string expression that you want to search for.

Compare: Optional numeric expression that defines the type of comparison. The value of this parameter can be 0 or 1. The default value of 1 specifies a text comparison that is not case-sensitive. The value of 0 specifies a binary comparison that is case-sensitive.

To avoid a run-time error, do not set the Compare parameter if the first return parameter is omitted.
