1  –  Input

       An integer.

       None.

       DTR> SET COLUMNS_PAGE = 132
       DTR> FN$WIDTH (132)

       FN$WIDTH (132) sets the terminal's width at 132 characters or
       columns. The SET COLUMNS_PAGE command ensures that any output
       produced by REPORT, PRINT, SUM, or LIST statements is spaced
       across the 132 columns.
