During an active monitoring session, if InterTest for CICS detects a potential problem with an application program, it will stop program execution and issue an Automatic Breakpoint (ABP) .
One such example is when a program attempts to write to the CICS Common Work Area (CWA); an area of storage defined within a CICS region that any user application can potentially utilize. Although the CWA can be considered a "public" area, while monitoring a program with InterTest, any attempt to write to this area will be perceived as a potential storage violation. In such a situation, InterTest will stop program execution and issue an automatic breakpoint. Any attempts to continue will be prevented unless the programmer takes some sort of corrective action.
