Example

   $ CREATE WEATHER.COM
   $ DECK
   $ FORTRAN WEATHER
   $ LINK WEATHER
   $ RUN WEATHER
   $ EOD
   $ @WEATHER

     In this example, the command procedure creates a command
     procedure called WEATHER.COM. The lines delimited by the DECK
     and EOD commands are written to the file WEATHER.COM. Then the
     command procedure executes WEATHER.COM.
