			==Usage==
			The following examples show usage of the CENTSPLT parameter:
			<ul>
			<li>The current date is May 23, 1996 with CENTSPLT=50; BASECENT=19 (from the current
			date, 1996). The date 11/23/90 needs conversion. Because 90 is greater than 50, the date expands to 11/23/1990, because BASECENT is unchanged. If the date were 11/23/05,
			because 05 is less than 50, so the date expands to 11/23/2005, because BASECENT is
			incremented.</li>
			<li>The date 11/23/98 needs conversion. Because 98 is greater than 50, the date expands to 11/23/1998, because BASECENT is unchanged. If the date were 11/23/02, then 02 is less than 50, so the date expands to 11/23/2002, because BASECENT is incremented.</li>
			</ul>
			<p>The <var>[[$DateCnv]]</var> and <var>[[$DateDif]]</var> functions have been modified to use these parameters. By default, they use whichever parameter is active.</p>
			<p>Alternatively, both these functions have two additional optional arguments (for <var>$DateCnv</var>, arguments 4 and 5, for <var>$DateDif</var>, arguments 5 and 6) that allow the specification of either a DEFCENT value or a CENTSPLT value (in that order) that are in effect for that one function call. Like the parameters, the arguments are mutually exclusive, so you can specify only one of them on a call. For example, to specify a CENTSPLT argument to <var>$DateCnv</var>, the call is:</p>
			<p class="syntax">%A = $DateCnv(fmt1,fmt2,datei,,%CENTSPLT)</p>
