Set Unconditional Breakpoints at All References to a Data Name

You can set unconditional breakpoints at all references to a data name from the Cross Reference section.

To display the Dataname Cross Reference, type l .dx in the command line or 6 in the Option # field on the Source Listing screen, as shown next, and press Enter.

CA InterTest for CICS V9.1 - PROTSYM FILE SOURCE LISTING DISPLAY COMMAND ===> l .dx Program= COBDEMO Option # Stmt # Margin= 01 Search= OPTS 1 Proc div 2 Work-stor 3 Link sect 4 D-map 5 Clst/Pmap More: + 6 Data xref 7 Proc xref 8 Err msgs 9 Srch fwd 10 Srch bwd PFKS 1 Help 2 3 End 4 Profile 5 Monitor 6 Menu 7 Backward 8 Forward 9 10 11 12 Status ------------------------------------------------------------------------------- _ 000477 CONTINUE-TASK. 000478**** TASKNUM *NOTE* FIELD MUST BE INITIALIZED _ 000479 ADD +1 TO TASKNUM. . . .

CA InterTest displays the Dataname Cross Reference section, as shown next.

Now type a u to the left of the data names for which you want to set unconditional breakpoints, as shown next, and press Enter.

CA InterTest for CICS V9.1 - PROTSYM FILE SOURCE LISTING DISPLAY COMMAND ===> Program= COBDEMO Option # Stmt # Margin= 01 Search= OPTS 1 Proc div 2 Work-stor 3 Link sect 4 D-map 5 Clst/Pmap More: + 6 Data xref 7 Proc xref 8 Err msgs 9 Srch fwd 10 Srch bwd PFKS 1 Help 2 3 End 4 Profile 5 Monitor 6 Menu 7 Backward 8 Forward 9 10 11 12 Status ----------------------------------------+-------------------------------------- _ DEF DATA NAMES REFERENCES _ 32 TASK-PROTCPF M421 909 919 _ 33 TASK-PROTHLF M422 761 _ 47 TASK-SL1 _ 49 TASK-SL2 u 30 TASK-STRUCTURE 391 448 496 520 658 867 879 925 993 _ 51 TASK-STRUCTURE-2 659 u 34 TASK-SWITCH 398 M438 M556

According to the previous example, CA InterTest will set breakpoints at every statement that references data names TASK‑STRUCTURE and TASK‑SWITCH.

To remove the breakpoints, overtype the U with x. You can remove all the breakpoints for a data name from the Cross Reference section, or you can selectively remove breakpoints at specific statements. You can also remove individual or multiple breakpoints from the Monitoring Status display. You might want to do this when you have a number of breakpoints set throughout a large program and do not want to hunt through the source listing for them.

If your source listing does not include the Cross Reference section, you can also set a breakpoint at all references to a data name from the Working‑Storage section where the data name is defined.

To display the definition, type the data name in the Search= field and press Enter.

When CA InterTest displays the definition, type a u to the left of the statement, as shown next, and press Enter.

CA InterTest for CICS V9.1 - PROTSYM FILE SOURCE LISTING DISPLAY COMMAND ===> Program= COBDEMO Option # Stmt # Margin= 01 Search= OPTS 1 Proc div 2 Work-stor 3 Link sect 4 D-map 5 Clst/Pmap More: + 6 Data xref 7 Proc xref 8 Err msgs 9 Srch fwd 10 Srch bwd PFKS 1 Help 2 3 End 4 Profile 5 Monitor 6 Menu 7 Backward 8 Forward 9 10 11 12 Status ------------------------------------------------------------------------------- _ 000035 03 TASK-SWITCH2 PIC 99. _ 000036 03 TASK-SWITCH3 PIC X. u 000037 03 TASKNUM PIC S9(5) COMP-3. _ 000038 03 TASKNUM-CHAR REDEFINES TASKNUM PIC X(3). _ 000039 03 TASK-TEXT. _ 000040 05 TASK-ID-NO PIC 9(3) COMP-3 VALUE 0. . . .

In this example, CA InterTest sets breakpoints at all references to TASKNUM.

To remove the breakpoints, overtype the U with x, or remove the breakpoints from the Monitoring Status display.
