They're pretty optimistic about how long this script will be in use:
``` if (l_y < 1900 || l_y > 9999) { l_err = 1 ; l_errstring = "Year is invalid."; } ```
``` if (l_y < 1900 || l_y > 9999) { l_err = 1 ; l_errstring = "Year is invalid."; } ```
Something has gone seriously wrong with human society if that ever actually happens.
