NOTES

SIXBIT is not part of any ASCI| standard. It is used by DECsystem-10 programs as a code
compression technique for the 64 character graphic subset of ASCII.

Teleprinters manufactured by Teletype Corporation, Skokie, |llinais, have used codes 175 (ALT)

and 176 for ESC. Programs may forgo the use of } (175) and ~ (176) in order to use these
codes as ESC on older teleprinters.

ASCII is a seven bit character code with an optional odd parity bit (200) added for many devices.
Programs normally use just seven bits internally; the 200 bit is either stripped or added so the
program will operate with either parity or non-parity generating devices.

1SO Recommendation R646 and CCITT Recommendation V.3 (International Alphabet No. 5) is
identical to ASCII except that number sign (043) is represented as £ instead of # and certain
characters are reserved for national use.
