- DDEESSCCRRIIPPTTIIOONN
- _E_x is the root of a family of editors: _e_d_i_t, _e_x and _v_i. _E_x
- is a superset of _e_d, with the most notable extension being a
- display editing facility. Display based editing is the
- focus of _v_i.
-
- If you have not used _e_d, or are a casual user, you will find
- that the editor _e_d_i_t is convenient for you. It avoids some
- of the complexities of _e_x used mostly by systems programmers
- and persons very familiar with _e_d.
-
- If you have a CRT terminal, you may wish to use a display
- based editor; in this case see _v_i(1), which is a command
- which focuses on the display editing portion of _e_x.

- The document _E_d_i_t: _A _t_u_t_o_r_i_a_l (USD:14) provides a comprehen-
- sive introduction to _e_d_i_t assuming no previous knowledge of
- computers or the UNIX system.
-
- The _E_x _R_e_f_e_r_e_n_c_e _M_a_n_u_a_l - _V_e_r_s_i_o_n _3._7 (USD:16) is a
- comprehensive and complete manual for the command mode
- features of _e_x, but you cannot learn to use the editor by
- reading it. For an introduction to more advanced forms of
- editing using the command mode of _e_x see the editing docu-
- ments written by Brian Kernighan for the editor _e_d; the
- material in the introductory and advanced documents works
- also with _e_x.

- duces the display editor _v_i and provides reference material
- on _v_i. In addition, the _V_i _Q_u_i_c_k _R_e_f_e_r_e_n_c_e card summarizes
- the commands of _v_i in a useful, functional way, and is use-
- ful with the _I_n_t_r_o_d_u_c_t_i_o_n.

- Originally written by William Joy
- Mark Horton has maintained the editor since version 2.7,
- adding macros, support for many unusual terminals, and other
- features such as word abbreviation mode.

- BBUUGGSS
- The _u_n_d_o command causes all marks to be lost on lines
- changed and then restored if the marked lines were changed.
-
- _U_n_d_o never clears the buffer modified condition.
-
- The _z command prints a number of logical rather than physi-
- cal lines. More than a screen full of output may result if
- long lines are present.
-
- File input/output errors don't print a name if the command
- line ``--'' option is used.
-
- There is no easy way to do a single scan ignoring case.
-
- The editor does not warn if text is placed in named buffers
- and not used before exiting the editor.
-
- Null characters are discarded in input files, and cannot
- appear in resultant files.
