FIND UPDATE

            LAS\FIND UPDATE [/OPT1 ...]

        The input index will first be appended with  the  new  observations  (if
        any) present in the input file. This saves time because a (much) smaller
        part of the input file is actually read. The current index is then reset
        and  recomputed  from  the  input  index (i.e. with old and new observa-
        tions), as usual.

        FIND UPDATE does not wait for new data, but  you  can  use  the  command
        NEW_DATA to do so.

        This keyword can be omitted if the SET FIND mode is UPDATE.
