Function:    Width123()

               The standard width of every column in the
               worksheet is 9, this setting can be overridden by
               this function.

  Syntax:      Width123(Col,Len)

  Arguments:   <Col> is the column to set the width of (starting
               from 0), <Len> is the desired width. It is
               recommended to always set the width to one
               character more that Clipper would use (eg. Dates
               require 9 places to display properly in 1-2-3
               instead of 8 in Clipper, Logicals would need 1 in
               Clipper, but use 2 chars to display properly in 1-2-3..).

  Returns:     Nothing.

  Usage:       * - Supposing the Worksheet file open...
               Width123(0,4)            && Col 'A' width to 4
               Write123(0,0,'Yo!')      && write some cell..
