	$Web_IsIndex_Num_Line is a short synonym for $Web_IsIndex_Parm_Num_Line.		<var>$Web_IsIndex_Num_Line</var> is a short synonym for <var>[[$Web_IsIndex_Parm_Num_Line]]</var>.

			Since isindex fields are more commonly called "URL parameters," you can use another synonym for this $function, <var>[[$Web_URL_Parm_Num_Line]]</var>.

			<var>$Web_IsIndex_Parm_Num_Line</var> takes two arguments and returns either the number of lines in the isindex field or a 0 indicating either that there were no lines in the isindex field or that some other error has occurred. Possible errors would be the isindex field not being found or the function being invoked on a non-web server thread.

			==Usage notes==
			<ul>
			<li>A line is considered to be a block of text that is terminated by either an ASCII carriage return (X'0D') or a carriage return followed by a line feed (X'0A'). This is what is ordinarily sent by a browser to mark the end of each line of a textarea input field.
			<li>For a discussion of isindex requests and data, see [[Janus Web Server application coding considerations#URL parameters or isindex data\|"URL parameters or isindex data"]].
			</ul>

			==Examples==
	A line is considered to be a block of text that is terminated by either an ASCII carriage return (X'0D') or a carriage return followed by a line feed (X'0A'). This is what is ordinarily sent by a browser to mark the end of each line of a textarea input field.

	This example checks if the number of lines returned in a textarea exceeds the size of the array meant to hold the input from the textarea.		This example checks if the number of lines returned in a textarea exceeds the size of the array meant to hold the input from the textarea.
