The hdate of 59461 represents October 19, 2003; the dformat of 1 allows it toreturn two-digit or four-digit years, and the yearopt of 5 specifies a sliding window for fourdigityears. Because of the yearopt setting, the startwin and endwin are calculated relative tothe current year (in this case 1997) by addition and subtraction.WRITE $ZDATE(59461,1,,5,90,10)The sliding window for displaying the year as two digits extends from 1/1/1907 to 12/31/2006.Thus Caché displays the date as 10/19/03.Date Range ExampleThe following example illustrates the use of mindate and maxdate. The dates are specifiedin $HOROLOG format, and represent the date range from 1/8/1950 to 4/10/2005.WRITE $ZDATE(59451,,,,,,40000,60000)displays as 10/09/2003.WRITE !,$ZDATE(39000,,,,,,40000,60000)WRITE !,$ZDATE(62000,,,,,,40000,60000)330 Caché ObjectScript Reference
