Interrupt BTEQ |
The break key command has the following syntax:
where:
<break_key> represents pressing the PA1 key on the mainframe keyboard.
<Unlocking_terminal> comprises the following sequence of steps:
1 Press RESET
2 Press PA1
3 Press RESET
4 Press PA1
Note: When BTEQ is in the process of displaying multi-page output for a query, the keyboard is not locked and pressing the PA1 key sends a user interrupt to BTEQ.
In contrast, when the TSO terminal is waiting for an outstanding request, the keyboard is locked to prevent input. To unlock the terminal keyboard and send a user interrupt to BTEQ, follow the sequence of steps above to unlock the terminal and interrupt BTEQ.
Single Break
The single break function interrupts BTEQ while it is processing a previous request. It is generated either by pressing the break key or pressing the sequence of keys that unlocks the terminal. On receipt of a single break, BTEQ displays:
*** PA1 key hit! Enter 'ABORT' to abort current operation
*** or 'EXIT/QUIT' to abort transaction and exit BTEQ:
At the input command prompt, enter CONTINUE, ABORT, EXIT, or QUIT.
Enter CONTINUE to recover from the interrupt and resume BTEQ as if the interrupt never occurred.
Enter ABORT to abort the previous request.
Enter either EXIT or QUIT to abort the transaction and terminate BTEQ.
