The ordering sequence assigned to characters or a group of characters when
they are sorted and ordered by a computer.

scripts (written in the shell command language).
command interpreter
A program that reads lines typed at the keyboard or from a file, and
interprets them as requests to execute other programs. The command

the execution of the program.
compiler

context analysis
The process of determining the proper shape of a character based on its
position in the word. For some languages, a character can have a different
shape if it is at the start of a word, in the middle of a word, at the end of
a word, or standing alone. Currently, context analysis is defined for the
Middle Eastern and North African Arabic languages.
control character or control code
A nonprinting member of a character set that produces action in a device.
In ASCII, control characters are those in the code range 0 through 31, and
127. These values and the space character, with code value 32, are not
Glossary
used for any other purpose. Code values 128 through 160 and 255 are also
treated as control codes in some cases, except in ISO 8859 where 255 is a
valid character. Most control characters can be generated by simultaneously
pressing a displayable character key and
