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

 The EXT (extend) command executes a line mode command while you are in
 change mode.  EDT interprets the remainder of the command line as a line
 mode command, executes the command, and reenters change mode
 automatically. The EXT command may not be used inside parentheses.

 Format: EXT line mode command
