Define the percentage and computed columns. The DEFINE statement for Pctsum specifies a column heading, a format, and a column width of 8. The PERCENT. format presents the value of Pctsum as a percentage rather than a decimal. The DEFINE statement for COMMENT defines it as a computed variable and assigns it a column width of 20 and a blank column heading. The FLOW option wraps the text for COMMENT onto multiple lines if it exceeds the column width.

   define pctsum / 'Percent of Sales' format=percent6. width=8;
   define comment / computed width=20 '' flow;
