    There was a Y2K bug in that version as you surmised.  (Ted
    Molczan discovered this bug back in January, and Bjoern
    Gimle discovered a similar bug in ALLCOLA in March).  COLA
    was updated on 1/24 and sent to a few people, including Ed
    Cannon who I believe posted it on his site.  I'll be sending
    it and ALLCOLA to Mike McCants within the hour, so anyone
    running COLA with a creation date prior to 1/24/2000 or
    ALLCOLA with a creation date prior to 3/28/2000 needs to
    upgrade.
    
    Sorry for the inconvenience,
    Rob
