proqrams to get HELP:
   minitab: %minitab
            MTB > help help
        MTB > stop         {to exit Minitab}
   spss:  %spss
     This will bring up a split screen: pgm/output windows, 'esc' key and
     '1' --> select the 'help' menu item 'esc' key and '0' --> select the
     'exit' menu item 'esc' key and '0' ... '9' --> other menu items

   sas:     %sas
       This will bring up a split screen for output and program editor.
       Then use arrows or tab to select Help>Extended Help To exit,go
       to FIle>Exit SAS/PC NOTES :  File + Lib Names
