Set Request Breakpoints

Now you are going to set request breakpoints to halt ASMDEMO prior to all CICS REWRITE commands.

You can set request breakpoints to halt a program before CICS commands and macros and other calls, such as calls to DL/I or DB2. The Request Breakpoint Selection menu lets you select specific types of commands and macros at which to set request breakpoints.

You can set request breakpoints prior to all CICS commands or prior to specific commands, such as File Control or Program Control commands. Request breakpoints make it easy for you to halt your program at various points so you can check program processing. For example, you can halt the program before every READ command, single‑step through the read instructions, and then check main storage to make sure the program has read the correct record.

For option 03 of the advanced demo, you need to set request breakpoints at all File Control REWRITE commands in ASMDEMO. To do this, use the ITST Primary Option Menus for monitoring, as discussed next.

  1. Enter the RBP command on the command line.
  2. Press Enter to continue.

    The Request Breakpoint Selection menu appears. Here you specify the type of request breakpoint, such as all CICS commands, File Control, Task Control, and so on.
