ActionCharacters Supported from a Source Listing Display or Breakpoint

You can perform the following list of the functions by entering a single character on your source listing. Each of these functions is described in later chapters.

Chapter	Action Character	Function
Using Breakpoints	u	Unconditional; sets an unconditional breakpoint.
	c	Conditional; sets a conditional breakpoint.
	v	Variable‑change; sets a variable‑change conditional breakpoint (for COBOL or Assembler programs).
	x	Remove; removes a breakpoint or removes a variable from the Keep window.
Breakpoint Activities	d	Display; displays program or variable storage at a breakpoint.
	k	Keep; keeps a variable in the Keep window.
	m	Modify; modifies a variable at a breakpoint.
	@	Display; displays the main storage area pointed to by a data item for a 24‑bit address.
	%	Display; displays the main storage area pointed to by a data item for a 31‑bit address.
Resume and Execution Options	g	Bypass; bypasses monitoring of an instruction at an automatic breakpoint.

Note: The v, d, @, %, k, and m functions should be entered next to a statement that references or defines the variable that you want to display, keep, or modify. If the statement references the variable, you must also position the cursor under the variable name before pressing Enter.

Shortcut Commands for CNTL Functions

To access a CNTL function, enter a code using the following format in the Option # field, and press Enter:

=nns  OR  =nnr

=: Required.
nn: Specifies function number (10 to 33) from the CNTL main menu.
s or r: Specifies setting or removing the option .

Note: While the CNTL shortcut commands are supported, you will find it easier to use the Monitoring Menus, available from Primary Option Menu Option 2 Monitoring.

The following table summarizes the Option # codes you can enter for the standard CNTL Selection Menu functions.

Option # Command	CNTL Selection Menu Function
=10s	Sets monitoring for the program displayed; same as PF5.
=10r	Removes monitoring, breakpoints, and all other options for the program displayed.
=11s and 11r	Sets and removes unconditional breakpoints.
=12s and 12r	Sets and removes conditional breakpoints.
=13s and 13r	Sets and removes request breakpoints.
=14s and 14r	Sets and removes Segmented Monitoring On option.
=15s and 15r	Sets and removes Segmented Monitoring Off option.
=16s and 16r	Sets and removes statement tracing and data monitoring.
=20s and 20r	Sets and removes Replace options.
=21s and 21r	Sets and removes Protection options.
=22s and 22r	Sets and removes Special options.
=23s	Sets Composite Support.
=24	Accesses the Indirect Commands facility.
=30	Shows the Status Display screen.
=31	Sets Utility Options screen.
=33	Resumes task execution.
