PRCB CLEAR LOCK (405)    HELP FRAME (9.2)

This option allows the user to clear a program lock and 
continue processing.  This option clears a lock that 
has been placed on batch transmission or on releasing 
the budget figures for a station.  This can occur when 
someone else is using the option and the system will 
not allow a second person to perform the same function, 
or when a system error or power problem interrupts a 
function.  Never proceed with further processing after 
a lock until you have used this option to clear the lock.
