            LAS\MODIFY Item [Values...]

        This is a general purpose command to edit and change the current  obser-
        vation header. Some actions are merely presentation "details", others do
        affect the information in the observation. Among these, RECENTER, WIDTH,
        IMAGE  and SWITCH_MODE are typically used only when the software did not
        agree with the hardware when the spectra was taken (i.e. when the infor-
        mation  in  the  observation  header is wrong). They should be used with
        caution.

        MODIFY actions are limited. You should use the SIC\ command LET to modi-
        fy  header  variables  which are not available within the MODIFY command
        (Caution: this is the rope to hang you).
