Library /sys$common/syshlp/dbg$help.hlb DEBUG, DISCONNECT, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    (Kept debugger only.) The DISCONNECT command releases a specified
    process from debugger control without terminating the process.
    This is useful if, for example, you have brought a running
    program under debugger control with a CONNECT command and you now
    want to release it without terminating the image. (In contrast,
    when you specify a process with the EXIT or QUIT command, the
    process is terminated.)

                                 CAUTION

       The debugger kernel runs in the same process as the image
       being debugged. If you issue the DISCONNECT command for this
       process, you release your process, but the kernel remains
       activated.

       This activation continues until the program image finishes
       running.

       If you install a new version of the debugger while one or
       more disconnected but activated kernels inhabit user program
       space, you can experience problems with debugger behavior if
       you try to reconnect to one of those kernels.
