DEFINE
/KEY
Examples
1.$ DEFINE/KEY PF3 "SHOW TIME" /TERMINATE
%DCL-I-DEFKEY, DEFAULT key PF3 has been defined
$
$ SHOW TIME
14-DEC-1994 14:43:59
In this example, the DEFINE/KEY command defines the PF3 key on
the keypad to perform the SHOW TIME command. DEFAULT refers to
the default state.
2.$ DEFINE/KEY PF1 "SHOW " /SET_STATE=GOLD/NOTERMINATE/ECHO
%DCL-I-DEFKEY, DEFAULT key PF1 has been defined
$ DEFINE/KEY PF1 " DEFAULT" /TERMINATE/IF_STATE=GOLD/ECHO
%DCL-I-DEFKEY, GOLD key PF1 has been defined
$
$
$ SHOW DEFAULT
DISK1:[JOHN.TEST]
In this example, the first DEFINE/KEY command defines the PF1
key to be the string SHOW. The state is set to GOLD for the
subsequent key. The /NOTERMINATE qualifier instructs the system
not to process the string when the key is pressed. The second
DEFINE/KEY command defines the use of the PF1 key when the
keypad is in the GOLD state. When the keypad is in the GOLD
state, pressing PF1 causes the current read to be terminated.
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.
