UPDATE

        LAS\UPDATE

    Update the LAST version of the observation in the R buffer in the output
    file. You can update only the last version. The  update  OVERWRITES  the
    observation.  This command MUST BE USED WITH CAUTION; in case of complex
    manipulations of observations, you may get confused and  erase  precious
    data.

    If  more space is needed (e.g., the new version has more header informa-
    tion), an error is returned. You MUST  then  WRITE  the  observation  to
    avoid loss of information.

    The only typical case where it may be used is in the following sequence:
        GET Number
        MINIMIZE or MODIFY
        UPDATE
