AmigaOS 4.0 - About OS4 - Commands

BREAK AmigaDOS
Purpose: To set attention flags in the specified process.
Format: BREAK <process> NAME=<name> [ALL | C | D | E | F]
Template: PROCESS/A/N, NAME/K, ALL/S, C/S, D/S, E/S, F/S
Path: C:BREAK
BREAK sets the specified attention flags for the <process> or <name> specified. Use the STATUS command to display the current process numbers and names.

C sets the Ctrl+C flag, D sets the Ctrl+D flag, and so on. ALL sets all of the flags from Ctrl+C to Ctrl+F. By default, only the Ctrl+C flag is set.

The action of BREAK is identical to selecting the relevant process by clicking in its window and pressing the appropriate Ctrl+key combination(s).

Ctrl+C is used as the default for sending a BREAK signal to halt a process. A process that has been aborted this way will display ***BREAK in the Shell window.

Ctrl+D is used to halt execution of a script file.

Ctrl+E is currently undefined.

Ctrl+F is used by programs that open windows. Sending these programs a Ctrl+F signal will cause them to activate their window and bring it to the front of all windows. Not all programs respond to Ctrl+F.

Example 1:

3.OS4:> STATUS
Process  3: Loaded as command: status
Process  5: Loaded as command: execute
Process  6: Loaded as command: wait
Process  7: Loaded as command: find
3.OS4:> BREAK 7
 sets the Ctrl+C attention flag for process 7. This is identical to selecting process 7 and pressing Ctrl+C.

Example 2:

3.OS4:> BREAK NAME=WAIT
 sets the Ctrl+C attention flag for the 'wait' command (process 6). This is identical to selecting process 6 and pressing Ctrl+C.

Example 3:

3.OS4:> BREAK 5 D
 sets the Ctrl+D attention flag for process 5.
