Setting the list cursor on a particular card (using either the mouse or the
arrow keys), and clicking on the Show action button will, if that card
is implemented, visualise the command of that particular card. (The cards
recognised by Read — see Section
— are all implemented, but with varying completeness.) The type of card and some information regarding the card are given in the ``Comment line'' at the top of the window. If applicable, a graphical aid
will be given in the Graph Window. This includes highlighting the segments
affected by voltage sources, transmission lines, two-port networks and
coupling cards; plotting the field points for radiation pattern (including
those requested by the XQ
card) and near-field calculations (including the line
cards). The position and direction of current sources are also displayed. Cards loaded from NEC using commas as spacers should, in most cases, be equally well interpreted by the Show action button. If commas are used, zeros can be left blank, but not in the first integer position.
