Library /sys$common/syshlp/ncphelp.hlb Prompting, Exiting the Prompting Sequence  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 You can exit a prompting sequence by responding with CTRL/Z for the
 prompt. This returns you to the NCP> prompt where you can then issue
 another NCP command. You can exit NCP directly from the prompting
 sequence by responding with CTRL/C or CTRL/Y.

 Responding to a parameter prompt or query with "_DONE" skips the
 remainder of the prompts or queries and performs the requested
 function with the parameters which have been entered up to that point.
