I'm looking for prolog routines that can do calendar arithmetic. That is, I need routines that can add/subtract an arbitrary number of days to a given date to produce a resultant date. If the calendar arithmetic routines are not available, a routine to convert dates to/from julian dates would be just as useful. Thanks in advance!! --Barry ----------------------------------------------------------------------- Barry Silk bcs@prc.unisys.com Unisys - Center for Advanced Information Technology (215) 648-2509 -----------------------------------------------------------------------
