Set Unconditional Breakpoints from Cross-Reference Sections

The Cross Reference sections of the PL/I listing allow you to set many breakpoints at once. You can set unconditional breakpoints from the sections in the listing:

• Data Name Cross Reference Table (L .DX or Option 1)
• Procedures Cross‑Reference (L .PX or Option 13)
• Labels Cross‑Reference (L .LX or Option 14)

To display a section, type the command on the command line or the number in the Option # field on the Source Listing screen, as shown next, and press Enter.

Setting Breakpoints at All Procedures and All Labels

To set unconditional breakpoints at all Procedure Names and All Labels, display the Cross Reference table using Option # 1 (or L .DX command), type U next to the "ATTRIBUTE/XREF TABLE" heading line and press Enter. A message prompts you to confirm the request for setting many breakpoints by pressing PF3.

To set breakpoints at all Procedure names only, go to the Procedures Xref section using Option # 13 (or L .PX command), and then type U next to the "PROCEDURE ATTRIBUTE/XREF TABLE" header line and press Enter.

To set breakpoints at all Labels only, display the Labels Cross Reference section using Option # 14 (or L .LX command), and then type a U next to the "LABEL ATTRIBUTE/XREF TABLE" header line and press Enter.

You can remove all of these breakpoints at once by typing an X on the appropriate heading line and pressing Enter, or you can remove them individually from the Status display (type R next to an entry) or one of the Cross Reference Sections of the Source Listing (type X).

Setting Unconditional Breakpoints at Data Items

From the Data Name Cross Reference Table section (Option 1) you can also set breakpoints next to individual data items. Display the section, scroll forward using PF8, and type U next to the data item.

You can remove the breakpoints from either the Source Listing display (overtype the U with x) or the Status display (type r next the breakpoint entry).
