The PROC TEMPLATE statement starts the TEMPLATE procedure. The DEFINE STYLE statement creates a new style definition called newstyle2. This STYLE statement defines the style element fonts. This style element is composed of three user-defined attributes: cellfont, headingfont, and titlefont. Each of these attributes describes a font.
