Set Unconditional Breakpoints

To begin, you will need to bring up the Source Listing display for the PL/I demo program. This was covered in the basic demo session.

1. Press PF4 to display the Profile panel. Verify that the Display titles is set to N and that the AutoKeep Display is ON. If not, change either or both of them and press Enter.

2. Press PF3 to return to the listing.

   Now you will set unconditional breakpoints at three procedure names. Setting unconditional breakpoints lets you halt the program so that you can set options and check the contents of data items.

3. Start by searching for the label READATA. Tab to the Search= field, type l readata in the command line and press Enter.

   The READATA label appears.

   You will set unconditional breakpoints at the statement:

   GOTO SENDMP00
   

4. Tab to the GOTO SENDMP00 statement.
5. Type u to the left of the statement, and press Enter.
