New;}}'/
      DATA CCD/'{\stylesheet{\f1\fs20 \snext0 Normal;}'/
      DATA CCE/'{\*\cs10 \additive Default Paragraph Font;}}'/
      DATA CCF/'{\info{\title (actual title) }}'/
C chooses either LETTER size

      DATA C4P/'\paperw11907\paperh16840\paperw16840\paperh11907'/
C then
      DATA
CCM/'\margl1134\margr0851\margt0851\margb0851\lndscpsxn'/
