The table shows that the character with code value 0 is a control character, 'called the NULL character. The end-of-text code ETXalso known as Control-Cwas inappropriate for a variety of reasons, while using Z as the control code to end a file is analogous to it ending the alphabet and serves as a very convenient mnemonic aid.

The "escape" character ESC, code 27for example, was intended originally to allow sending other control characters as literals instead of invoking their meaning.

Unix and Unix-like systems, and Amiga systems, adopted this convention from Multics. The character column shows the key s that must be pressed. Notice that the character 'A' has the code value of 65, 'B' has the value 66, and so on.

The name "Carriage Return" comes from the fact that on a manual typewriter the carriage holding the paper moved while the position where the typebars struck the ribbon remained stationary.

Note, after the escape backslash, a leading zero should not be included in writing octal or hexadecimal numbers.

Because the keytop for the O key also showed a left-arrow symbol from ASCII, which had this character instead of underscore , a noncompliant use of code 15 Control-O, Shift In interpreted as "delete previous character" was also adopted by many early timesharing systems but eventually became neglected. The "escape" character ESC, code 27 , for example, was intended originally to allow sending other control characters as literals instead of invoking their meaning. At most three octal digits or at most two hexadecimal digits are needed. Note, after the escape backslash, a leading zero should not be included in writing octal or hexadecimal numbers. Consequently, a character data type may optionally represent signed values; however, for now, we will assume that character data types are unsigned, i. By the time so-called "glass TTYs" later called CRTs or terminals came along, the convention was so well established that backward compatibility necessitated continuing the convention. A historically common and still prevalent convention uses the ETX code convention to interrupt and halt a program via an input data stream, usually from a keyboard. Remember, a digit character and the equivalent number have different representations. Of course, the internal machine representation of characters is in equivalent binary form. Notice that the character 'A' has the code value of 65, 'B' has the value 66, and so on.

The entire carriage had to be pushed returned to the right in order to position the left margin of the paper for the next line. The inherent ambiguity of many control characters, combined with their historical usage, created problems when transferring "plain text" files between systems.

Similarly, the digit symbol characters '0' through '9' are also in an increasing contiguous sequence starting at the code value The Unix terminal driver could only use one code to erase the previous character, this could be set to BS or DEL, but not both, resulting in a long period of annoyance where users had to correct it depending on what terminal they were using shells that allow line editing, such as kshbashand zshunderstand both.

The ASCII code associates an integer value for each symbol in the character set, such as letters, digits, punctuation marks, special characters, and control characters. Consequently, a character data type may optionally represent signed values; however, for now, we will assume that character data types are unsigned, i.

Over time this meaning has been co-opted and has eventually been changed.
