One-screen ASCII Chart

The following ASCII chart contains ALL the ASCII values, each with the
control function or printable character assigned to it.

Some so-called ASCII charts for IBM-type microcomputer systems show
printable characters (smiling faces, musical notes, etc.) for values in
the control range, and some show characters for values above 128. To be
blunt, such charts are simply wrong. The ONLY true ASCII characters are
those listed next to the SAME values on charts for ALL computer systems,
from an Apple II to a Cray, and those are the characters shown below.

Standard U.S. descriptions of ASCII use two- and three-letter names for
the control codes; ISO uses only two-letter names. The letters that ISO
omits are given in lowercase here (see note below chart).

I have put the hexadecimal column and row labels in the form of a cross,
rather than at the extreme top and left, for easier reference.

This chart fits quite nicely on a DOS/Un*x text screen, and you can write
a simple batch file or script that will display it any time you need to
look up a character or control code.
