[ Type code = N ] When following a Y code, specifies a Yes/No field with "N" default (and pre-display). Otherwise, like # but does not display a "0" if nothing entered or supplied, and does display one blank after the marker characters. This is a useful alternative to the # code when the screen may be cluttered by the display of many fields containing 0 (e.g. "0", "0.00", "$0", etc. (See "B" to display the blanking.)
