STANDARD 7-BIT COMMUNICATION CODES (ANSCII) 1
NOTES:
The characters .... \ t ~ [] are ANSCII
characters that do not appear in any of the
EBCDIC-based character sets, though they
are shown in the EBCDIC table.
The characters I- I..., appear in the 63- and
89-character EBCDIC sets but not in either
of the ANSCII-based sets. However, Xerox
software
translates the characters
into ANSCII characters as follows:
EBCDIC ANSCII
1
\ (6-0)
1
I (7-12)
-,
- (7-14)
The EBCDIC cantrol codes in columns 0
and 1 and their binary representation are
exactly the same as those in the ANSCII
table, except for two interchanges: LF /NL
with NAK, and HT with ENQ.
4 Characters enclosed in heavy lines are
included only in the standard 63- and
89-character EBCDIC sets.
These characters are included only in the
standard 89-character EBCDIC set.

1 Most significant bit, added for 8-bit format, is either 0 or even parity.
Columns 0-1 are cantral codes.
Columns 2-5 correspond to the 64-character ANSCII set.
Columns 2-7 correspond to the 95-character ANSCII set.
On many current teletypes, the symbol
is
(5-i4)
is (5-15)
is ESC or ALTMODE control (7-14)
and none of the symbols appearing in columns 6-7 are provided. Except for the three
symbol differences noted above, therefore, such teletypes provide all the characters in
the 64-character ANSCII set. (The Xerox 7015 Remote Keyboard Printer provides the
64-character ANSCII set also, but prints A as fl.)
