          This index contains all the  MALLARD BASIC  keywords as supplied 
          with the PCW, in alphabetical order. Those dealt with on this course 
          disc are marked * and opposite each of these keywords is shown the 
          file or files in which the keyword is discussed. Use of the keyword
