The detach command quits the debugger. All breakpoints are removed before detaching. The process number, num, refers to MULTI's internal process slot number, not the operating system's pid number for the process. If the process is a child of the debugger, and not attached to in the first place, its parent process id is set to one. If no process slot number is given, then the current process is used. After a process is detached, the window associated with it disappears. See also attach.
