Lists the currently defined breakpoints, including the action taken when the specified breakpoint is activated. If no action is defined, z/OS® Debugger displays the NULL command.

AT_command: A valid AT command that includes at least one operand. The AT command must be complete except that the every_clause and command are omitted.
ENABLED: Restricts the list to enabled breakpoints. The default is to list both enabled and disabled breakpoints.
DISABLED: Restricts the list to disabled breakpoints. The default is to list both enabled and disabled breakpoints.
ALLOCATE: Lists currently defined AT ALLOCATE breakpoints.
APPEARANCE: Lists currently defined AT APPEARANCE breakpoints.
CALL: Lists currently defined AT CALL breakpoints.
CHANGE: Lists currently defined AT CHANGE breakpoints. This displays the storage address and length for all AT CHANGE subjects, and shows how they were specified (if other than by the %STORAGE function).
DATE: Lists currently defined AT DATE breakpoints.
DELETE: Lists currently defined AT DELETE breakpoints.
ENTRY: Lists currently defined AT ENTRY breakpoints.
EXIT: Lists currently defined AT EXIT breakpoints.
GLOBAL: Lists currently defined AT GLOBAL breakpoints for the specified AT-condition.
LABEL: Lists currently defined AT LABEL breakpoints.
LINE: Lists currently defined AT LINE or AT STATEMENT breakpoints. LINE is equivalent to STATEMENT.
LOAD: Lists currently defined AT LOAD breakpoints.
OCCURRENCE: Lists currently defined AT OCCURRENCE breakpoints.
OFFSET: Lists currently defined AT OFFSET breakpoints.
PATH: Lists currently defined AT PATH breakpoints.
STATEMENT: Is equivalent to LINE.
SUSPENDED: Lists all suspended breakpoints.
TERMINATION: Lists currently defined AT TERMINATION breakpoint.

If the AT command type (for example, LOAD) is not specified, LIST AT lists all currently defined breakpoints (both disabled and enabled).

Usage notes

To display a global breakpoint, you can specify an asterisk (*) with the LIST AT command or you can specify a LIST AT GLOBAL command. For example, if you want to display an AT ENTRY * breakpoint, specify:
```
LIST AT ENTRY *;
or
LIST AT GLOBAL ENTRY;
```
If you have only a global breakpoint set and you specify LIST AT ENTRY without the asterisk (*) or GLOBAL keyword, you get a message saying there are no such breakpoints.
The LIST AT command cannot be used while you replay recorded statements by using the PLAYBACK commands.

Examples

Display information about enabled breakpoints defined at block entries.
```
LIST AT ENABLED ENTRY;
```
Display information about global DATE breakpoint entries.
```
LIST AT DATE *;
```
Display breakpoint information for all disabled AT CHANGE breakpoints within the currently executing program.
```
LIST AT DISABLED CHANGE;
```
The current programming language setting is C. Here are some assorted LIST AT commands.
```
LIST AT LINE 22;
```
or
```
LIST AT OCCURRENCE SIGSEGV;
```
or
```
LIST AT CHANGE structure.un.m;
```
