Breakpoint Activities › The Backtrace Facility › Example

Example

To use the information in the statement block columns, first look at the last entry, as in the previous screen:

#897.0... Bkpt

This block answers the question: How did I get to the current breakpoint? In this case, the program entered statement 897 and executed all of the machine instructions up to the current breakpoint.

The next question you might ask is: How did statement 897 receive control? To answer this question, you must look at the preceding statement block:

#887.0...#888.1

The statement number in the right column, 881.1, is the statement that caused a branch to statement 897.

Note: You might see a statement branch to itself, as in the following example from the previous figure:

    #812.0...#813.0 ç
 è #813.0...#818.0

This happens when a CICS command is issued and execution was returned to the same statement.
