/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.
