equivalence-string
Specifies the command string that you want assigned to the
function key. To preserve spaces and lowercase characters,
enclose the string in quotation marks (" ").
1.2 – Qualifiers
1.2.1 /ECHO
/ECHO
/NOECHO
Specifies whether LATCP displays the command string on your
screen when you press the key. If you do not specify the /ECHO
or /NOECHO qualifier, the default is that the command string
will be displayed. You cannot use /NOECHO with the /NOTERMINATE
qualifier.
1.2.2 /IF_STATE
/IF_STATE=state-name
Specifies the state that must be set (for example, the GOLD
state) for the key definition to work. Lets you assign
alternative meanings to keys when the specified state is set.
See the discussion of the /SET_STATE qualifier. If you omit the
/IF_STATE qualifier, LATCP uses the current state. The state name
is an alphanumeric string. States are established with the /SET_
STATE qualifier.
1.2.3 /LOCK_STATE
/LOCK_STATE
/NOLOCK_STATE
Specifies that the state set by the /SET_STATE qualifier remain
in effect until explicitly changed. If you use the /NOLOCK_STATE
qualifier, the state set by /SET_STATE remains in effect only
for the next definable key that you press or for the next read-
terminating character (such as Return or Ctrl/Z) that you type.
You can specify the /LOCK_STATE qualifier only with the /SET_
STATE qualifier. If you do not specify the /LOCK_STATE or
/NOLOCK_STATE qualifier, the default is that the state set by the
/SET_STATE qualifier remains in effect until explicitly changed.
1.2.4 /LOG
/LOG
/NOLOG
Specifies whether LATCP displays a message confirming that the
command was executed. If you do not specify the /LOG or /NOLOG
qualifier, the default is that no message will be displayed.
1.2.5 /SET_STATE
/SET_STATE=state-name
Causes the specified state to be set when you press the defined
key. The state name can be any alphanumeric string (for example,
GOLD). Use the DEFINE/KEY/IF_STATE=state-name command to
associate new meanings for keys when the specified state is set.
See the example for the DEFINE/KEY command.
If you omit the /SET_STATE qualifier, the current state that was
locked remains in effect.
1.2.6 /TERMINATE
/TERMINATE
/NOTERMINATE
Specifies whether the command string will be terminated
(processed) when you press the function key. The default is
/NOTERMINATE, which allows you to press other keys before the
command string is processed. Pressing Return has the same effect
as using /TERMINATE.
The /NOTERMINATE qualifier allows you to create key definitions
that insert text into command lines, after prompts, or into other
text that you are typing.
1.3 – Example
LATCP> DEFINE/KEY PF4 "SHOW NODE " /NOTERMINATE/SET_STATE=GOLD
LATCP> DEFINE/KEY PF4 "/ALL"/IF_STATE=GOLD/TERMINATE
The first DEFINE/KEY command in this example assigns the SHOW
NODE command to function key PF4. To process the SHOW NODE
command, you must press Return after pressing PF4. Note the
space after the word NODE in the first DEFINE/KEY command. This
space allows you to enter a node name after pressing PF4. When
you press Return, the SHOW NODE command is processed. If the
space is omitted, LATCP does not recognize the command (SHOW
NODE). The state is set to GOLD; that state will be in effect
for the next key that you press.
The second DEFINE/KEY command defines the use of the PF4 key
when the keypad is in the GOLD state. When you press PF4 twice,
the SHOW NODE/ALL command is processed.
