STAMP

        ANALYSE\STAMP NX [NY] [/LABEL SCAN|NUMBER|SOURCE|LINE [...] ]

    This command is intended to have a quick look at all the observations in
    the  index.   It  makes a plot of all the observations in the index, ar-
    ranged in a "map" of NX by NY observations. (If the index contains  many
    observations,  they  will be very small, hence the name of the command).
    The command does not require that X and Y scales be fixed.

    Command POPUP allows a selective zooming of any observation displayed by
    command STAMP.
