Attach the terminal to another process.  This transfers control from your
 current process to the specified process.  The current process (running
 DECNET_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.
