Library /sys$common/syshlp/edthelp.hlb SET, FNF  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Format: SET [NO]FNF

 The SET FNF option controls whether or not an informative message is
 displayed when you attempt to edit a non-existing file.  NOFNF opens a
 new file but gives no message.
