       Display  the name of molecules and transitions found in the specified
    catalog.

       Note: the whole plot is redrawn. Displayed lines are not simply over-
    laid on the current existing plot.

    Default  is to use the GAG\LECULE file, distributed with ASTRO but a us-
    er-defined catalog can also be specified. This file must be a text  file
    with entries:
        Freq   'chain'
        where Freq is the rest frequency in GHz and 'chain' the line name to
        be plotted by GreG, between single quotes. Example:
        88.632  'HCN'
        89.081  'HCO\u+'
    Another supported format is "Comma Separated Value", as produced by many
    spreadsheet processors, i.e.
