<paragraph id="par_id3153126" role="paragraph" xml-lang="en-US"> <emph>Start: </emph>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.<comment>see i17928</comment></paragraph>
<paragraph id="par_id3145609" role="paragraph" xml-lang="en-US"> <emph>Text1:</emph> The string expression that you want to search.</paragraph>
<paragraph id="par_id3147559" role="paragraph" xml-lang="en-US"> <emph>Text2:</emph> The string expression that you want to search for.</paragraph>
<paragraph id="par_id3154758" role="paragraph" xml-lang="en-US"> <emph>Compare:</emph> 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.<comment>fixes i17929</comment></paragraph>
<paragraph id="par_id3153361" role="paragraph" xml-lang="en-US">To avoid a run-time error, do not set the Compare parameter if the first optional parameter is omitted.</paragraph>
