                                           RUNTIME [DUAL MODE]
     
     NAME RUNTIME - Show the time it takes to run a command.
     
     SYNTAX
     
     runtime [/R | /H | /?] command arguments
     
     USAGE
     
     Runtime is  used to  show how  long it  takes  to  run  a
     command. Runtime  shows the  result  in  hours,  minutes,
     seconds and hundredths of seconds. Runtime works with all
     types of  executable files,  including .CMD  in OS/2  and
     .BAT in  DOS. If  the arguments  given to command contain
     arguments applicable to runtime, runtime interprets them,
     but passes them also to command. E.g. runtime mem -? sets
     the help option on for both runtime and mem.
     
     The internal  commands to shell such as dir, echo are not
     executable files and cannot be direcly run by runtime. If
     you want  to time  the dir-command  for example, you must
     start the shell first. The command to run is:
     C:>runtime cmd /c dir
     The /c  command instruct  the shell  to exit  immediately
     after it  has processed the commands on the command line.
     Without the  /c-switch the new command shell would remain
     in memory unnecessarily.
     
     You can also use runtime to keep time of your activities.
     E.g. runtime  "favourite-game", would give you, after you
     finished, the time you have played.
