UPDATE

        LAS\UPDATE

    Update the LAST version of the observation in the R buffer in the output
    file  ;  the  update OVERWRITES the observation. If more space is needed
    (e.g., the new version has more header information),  an  error  is  re-
    turned.  You  MUST  then WRITE the observation to avoid loss of informa-
    tion. You can update only last versions. This command MUST BE USED  WITH
    CAUTION  ; in case of complex manipulations of observations, you may get
    confused and erase precious data.

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