Using Breakpoints › Conditional Breakpoints › Set Conditional Breakpoints from the Source Listing

Set Conditional Breakpoints from the Source Listing

To set conditional breakpoints, specify the location and then the condition. Following these steps, specify one or more locations directly from the Source Listing.

1. Enter c in column 1 of any line in:
   • Your program listing (next to a paragraph, label, or executable code)
   • The Procedure Names section of the COBOL Cross‑Reference listing (for all paragraphs or selected paragraphs)
   • The Cross‑Reference section of COBOL, Assembler, or PL/I programs (next to a data name, label, or all labels)
   • If you enter c next to a data name in the Cross‑Reference section, the breakpoint takes effect at all locations where the item is referenced.
   • If you enter c next to the Procedure‑Names line in the Procedure names section of the COBOL Cross‑Reference listing or next to the Symbol line in the Cross‑Reference section of the Assembler listing, the breakpoints takes effect at all paragraph names or labels.

     Note: You can specify more than one c before pressing Enter.

2. Optionally, select Option # 12 Breakpoint Options to set options for your conditional breakpoints.
3. Press Enter.

Another way of specifying the same condition for multiple locations in your program is to use the ITST menus to specify both the locations and the conditions. For details, see Set Conditional Breakpoints from the Menus later in this chapter.

To set conditional breakpoints that apply to multiple locations in a program, follow these steps:

1. Enter a c in column 1 of each line in your source code at which you want to set a conditional breakpoint.
2. Press Enter. CA InterTest for CICS displays the first conditional breakpoint locations screen.
3. Specify one or more conditional breakpoint locations. CA InterTest for CICS displays a Conditional Breakpoint menu.

   Note: For more information on completing this screen, see Set Conditional Breakpoints from the Menus.

The For Location field indicates the statement number with the source code at which you specified c on the Source Listing display. Typing an S in the drop monitoring on a true condition field causes monitoring to be dropped for the rest of the current task when the conditional breakpoint is true.

Note: The For Location field does not display when you specify the location using the menus.

Press Enter after completing the Conditional Breakpoint menu. CA InterTest for CICS sets the conditional breakpoints and returns you to the Source Listing display.

Notes:

• Conditional Breakpoint menus for Assembler and PL/I programs and the complex Conditional Breakpoint menu for COBOL programs have additional entry fields.
• To replace an unconditional breakpoint with a conditional breakpoint, you must first remove the u before specifying the c. To remove the u, overtype it with x, and press Enter. To place a conditional breakpoint at that location, enter c where the u was, and press Enter.

Set Conditional Breakpoints from the Menus

Conditional breakpoints are set from the same Monitoring submenus used to set monitoring and unconditional breakpoints. Follow the same steps given in Set Conditional Breakpoints from the Menus. However, instead of entering s next to the UBP option, enter s next to the CBP option for conditional breakpoints.

First, CA InterTest for CICS displays the Conditional Locations screen.

This screen is similar to the screen used to specify unconditional breakpoints, and you should enter the information in the same way. For details, see Set Unconditional Breakpoints from the Menus later in this chapter.

One special feature lets you set a conditional breakpoint at all instructions. Enter an x in the All Instructions field to request this option, as shown in the previous example. If you request the All Instructions option and set a variable‑change breakpoint, the breakpoint takes effect whenever the value of the variable changes.

After specifying the breakpoint locations, press Enter to display the Conditional Breakpoint screen. On this screen specify the condition that must be satisfied for the breakpoint to take effect.

There are two versions of the Conditional Breakpoint screen: a simplified version for COBOL users, and a detailed version for PL/I and Assembler users and for those COBOL users who prefer this version. Using either version you specify the condition in this format:
