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
