Basic COBOL Batch Demo Session › Abend Occurs

Abend Occurs

The demo program is executing and CA InterTest detects an error at the ADD instruction. Execution of that ADD instruction triggers an S0C7 abend, which CA InterTest prevents.

At the abend, the following events occur:

• The appropriate program listing causing the error is activated (if the program was not displayed earlier).
• The program positions itself at the statement causing the error.

  

  When CA InterTest stops program execution, we say that it halts the program at a breakpoint. This is done automatically when an abend occurs, or CA InterTest halts a program at a breakpoint that was set by you.

When an abend occurs:

• A small blue arrow appears in the ruler to the left of the line causing the error, and the line is highlighted.
• The status in the InterTest Debug view now displays a diagnostic message.

  This message explains that the error was caused by improperly formatted data. Since Add +1 To TaskNum triggered the breakpoint, it is likely that TASKNUM contains improperly formatted data.
