It is often useful to be able to set an integer variable to the number of days which a DATE differs from the most current DATE of the database: integer base base:= 10/19/1997 .. And then use the variable, base, in the scan logic. One may wish to test scans against days on which significant events occurred, like a 500 point drop in the DOW. A user should not have to determine how many days ago a given DATE was. This is error prone and time consuming especially when months may have passed. Also, a scan logic file which one might wish to re-run for whatever reason produces different results as days pass, because the current day, ( as in close(0) ) has changed. Please ignore this comment if the ability to do this is in Release 2.
