The following table of the ANSI X3.64 encodings is the result of some work I
|
|
|
did a few years ago for BYTE magazine. BYTE made this table available for
|
|
|
download from several bulletin-board systems, so I see no reason why it cannot
|
|
|
be posted here for whatever private use you care to make. Just don't expect
|
|
|
to make a profit selling copies of it without paying royalties to McGraw-Hill.
|
|
|
|
|
|
Oh, by the way, the equivalent ISO standard is DP-6429.

article in the February 1983 BYTE, especially pages 214 through 224.

Format Effectors versus Editor Functions
|
|
|
|
|
|
A format effector specifies how the final output is to be created.
|
|
|
An editor function allows you to modify the specification.
|
|
|
|
|
|
For instance, a format effector that moves the "active position" (the
|
|
|
cursor or equvalent) one space to the left would be useful when you want to
|
|
|
create an overstrike, a compound character made of two standard characters
|
|
|
overlaid. Control-H, the Backspace character, is actually supposed to be a
|
|
|
format effector, so you can do this. But many systems use it in a
|
|
|
nonstandard fashion, as an editor function, deleting the character to the
|
|
|
left of the cursor and moving the cursor left. When Control-H is assumed to
|
|
|
be an editor function, you cannot predict whether its use will create an
|
|
|
overstrike unless you also know whether the output device is in an "insert
|
|
|
mode" or an "overwrite mode". When Control-H is used as a format effector,
|
|
|
its effect can always be predicted. The familiar characters carriage
|
|
|
return, linefeed, formfeed, etc., are defined as format effectors.

NOTES ON THE DEC VT100 IMPLEMENTATION
|
|
|
|
|
|
In the case of the popular DEC VT100 video-terminal implementation,
|
|
|
the only mode that may be altered is the linefeed/newline (LNM) mode.
|
|
|
Other modes are considered permanently set, reset, or not applicable
|
|
|
as follows:
|
|
|
|
|
|
Set: ERM
|
|
|
Reset: CRM, EBM, FEAM, FETM, IRM, KAM, PUM, SRTM, TSM
|
|
|
N/A: GATM, HEM, MATM, SATM, TTM, VEM
|
|
|
|
|
|
Control sequences implemented in the VT100 are as follows:
|
|
|
|
|
|
CPR, CUB, CUD, CUF, CUP, CUU, DA, DSR, ED, EL, HTS, HVP, IND,
|
|
|
LNM, NEL, RI, RIS, RM, SGR, SM, TBC
|
|
|
|
|
|
plus several private DEC commands.
|
|
|
|
|
|
Erasing parts of the display (EL and ED) in the VT100 is performed thus:
|
|
|
|
|
|
Erase from cursor to end of line Esc [ 0 K or Esc [ K
|
|
|
Erase from beginning of line to cursor Esc [ 1 K
|
|
|
Erase line containing cursor Esc [ 2 K
|
|
|
Erase from cursor to end of screen Esc [ 0 J or Esc [ J
|
|
|
Erase from beginning of screen to cursor Esc [ 1 J
|
|
|
Erase entire screen Esc [ 2 J
|
|
|
|
|
|
The VT100 responds to receiving the DA (Device Attributes) control
|
|
|
|
|
|
Esc [ c (or Esc [ 0 c)
|
|
|
|
|
|
by transmitting the sequence
|
|
|
|
|
|
Esc [ ? l ; Ps c
|
|
|
|
|
|
where Ps is a character that describes installed options.
|
|
|
|
|
|
The VT100's cursor location can be read with the DSR (Device Status
|
|
|
Report) control
|
|
|
|
|
|
Esc [ 6 n
|
|
|
|
|
|
The VT100 reports by transmitting the CPR sequence
|
|
|
|
|
|
Esc [ Pl ; Pc R
|
|
|
|
|
|
where Pl is the line number and Pc is the column number (in decimal).

The complete document describing the standard, "ANSI X3.64-1979:
|
|

Additional Controls for Use with the American National Standard
|
|
|
Code for Information Interchange," can be ordered for $13.50 (plus
|

$4 postage) from

It's best to read the full standard before using it. It also helps
|
|
|
to have copies of the related standards "X3.4-1977: American
|
|
|
National Standard Code for Information Interchange" (the ASCII
|
|
|
standard) and "X3.41.1974: Code-Extension Techniques for Use with
|
|
|
the 7-Bit Coded Character Set of American National Standard for
|
|
|
Information Interchange."
|

|
|
|
|
See also the chapter "Using Extended Screens and Keyboard Control"
|
|
|
in the IBM PC-DOS manuals, especially for the coding for character
|
|
|
attributes.
