Enter a third break to terminate BTEQ. Alternatively, entering either EXIT or QUIT after the first break also terminates BTEQ.
The behavior above is for console BTEQ only. Interrupt and Abort functions are available in BTEQWIN on the Sessions menu; CTRL+C is undefined in BTEQWIN.
Triple-breaks can be used to end batch more or interactive mode BTEQ execution. However, for BTEQ to recognize a triple-break scenario, the breaks (pressing CTRL+C key) need to happen fairly quickly, or else BTEQ may recognizing them as single breaks. So, pressing and holding down CTRL+C can be used to effectively simulate the triple-break scenario.
