           PLTTEK is an interactive program to display plots created by
        CTOUR on terminals supporting TEKTRONIX 4010 emulation. When
        invoked, the program simply prompts for the name of a plot
        file, and proceeds to display it on the terminal. After the
        plot is completed, the terminal bell will ring. Pressing the
        "return" then terminates the program. Prior to plotting, the
        program sends an escape sequence appropriate to place DEC
        VT240 series terminals in 4010 emulation mode. Upon termination
        an escape sequence to return to native emulation is sent. This
        sending of escape sequences can be eliminated by appending
        "/NOEM" to the plot file name, which would be appropriate for
        a terminal already in 4010 mode. The plot will be scaled to fit
        on the display regardless of the size requested at plot creation
        time. If a "/R" is appended to the end of a plot file name, then
        the plot will be rotated by 90 degrees, which sometimes allows a
        better fit of the plot to its allowed space. On UNIX systems use
        of the directory delimiter "/" interferes with interpretation of
        the "/NOEM" and "/R" switches, thus one should only specify file
        names of files resident in the current working directory, where
        no "/" other than for the switches will be present. Note that this
        type of graphic display is orders of magnitude slower than VIEWPLT,
        however in some instances it may be the only way to see a plot;
        as for example, when one is working at home from a "dumb" terminal.
        Also note that changing terminal emulation modes sometimes alters
        behavior of terminals. After viewing the plots, it may be necessary
        to log off and back in again, possibly powering down the terminal
        in between, or to reissue terminal initialization commands
        explicitly.
