Changing the Current Set with the focus Command

You can use the focus command to change the current process set, which is the set of processes whose debuggers receive the remote command entered at the root debugger:

focus_command

: focus expression

| focus all

| focus

The first form of the command sets the current process set to the set resulting from the evaluation of the given expression. The second form sets the current process set to the set that includes all processes. The third form displays the current process set.
