Navigate the Statement Trace Table

Once statement information is saved in the trace table, use the PREV and ADVANCE commands to determine the execution path of the program, by stepping backward and forward through the executed statements.

Use the PREV, or P, command to cause the display to back up one or more entries in the statement trace table. Consider the following breakpoint:

    CA InterTest for CICS r8.5  - PROTSYM FILE SOURCE LISTING BREAKPOINT           
COMMAND ===> prev

The PREV command will back up to the previous entry in the table, resulting in the following display:

Statement number 524 was the last statement executed prior to the abend at statement number 533. To back up 10 entries in the table, specify PREV 10. After using the PREV command to back up one or more entries in the statement trace table, use the ADVANCE, or A, command step forward through the table. Return at any time to the current statement using the CS command or the clear key.
