Attach the terminal to another process.  This transfers control from your
 current process to the specified process.  The current process (running
 DECNET_LOC_REGISTER.EXE) is placed in a hibernation state.

     ATTACH [process-name]

 If you specify the optional process name, the terminal is attached to that
 process.  The SHOW PROCESS and SHOW SYSTEM commands can be used to determine
 process names.

 If you do not specify the optional process name, the terminal is attached
 to the parent (owner) process for the current process.
