    Dear Jack,

    The Gflash documentation needs to be updated. The files that it
    creates start with "GSEG" and not "GNFB". These files are written to
    whatever path the command "ncargpath tmp" reports (most likely

    By default, however, these segment files are deleted after WISS is
    closed. You need to set the Ngmisc parameter "SS" to something other
    than the default value of 1 to cause the segments *not* to be deleted.
    For example, you can add the following to your code segment:

    *** activate WISS
            CALL GOPWK(9,1,3)

    *** Don't delete segment files
            CALL NGSETI('SS',0)

    *** start storage of llu plot commands
            CALL GFLAS1 (1)

    In addition, if you want to change the location and/or the root string
    used for the segment files, you can set the Ngmisc parameter "SE".
    For example, if you have:

            CALL GOPWK(9,1,3)
            CALL NGSETI('SS',0)
            CALL NGSETC('SE','GNFB')

    Then your segment files will be written to your current working directory,
    with the prefix "GNFB".

    For more information on these and other Ngmisc parameters, please see
    the man page for ngmisc_params.

    We will update the Gflash documentation as soon as possible.
