If you press the PF1 key twice, the system displays and
     processes the SHOW DEFAULT command.

     The word DEFAULT in the second line of the example indicates
     that the PF1 key has been defined in the default state. Note
     the space before the word DEFAULT in the second DEFINE/KEY
     command. If the space is omitted, the system fails to recognize
     DEFAULT as the keyword for the SHOW command.

   3.$ SET KEY/STATE=ONE
     %DCL-I-SETKEY, keypad state has been set to ONE
     $ DEFINE/KEY PF1 "ONE"
     %DCL-I-DEFKEY, ONE key PF1 has been defined
     $ DEFINE/KEY/IF_STATE=ONE PF1 "ONE"
     %DCL-I-DEFKEY, ONE key PF1 has been defined

     This example shows two ways to define the PF1 key to be "ONE"
     for state ONE.

     The second DEFINE/KEY command shows the preferred method for
     defining keys. This method eliminates the possibility of
     error by specifying the state in the same command as the key
     definition.
