Standard Characters

KCL supports all standard and semi-standard characters listed in Section 2.2.1 of the Common Lisp Reference Manual . Non-printing characters have the following character codes.

       Character        Code  (in octal)
       --------------------------------
       #\Space                 040
       #\Newline               012
       #\Backspace             010
       #\Tab                   011
       #\Linefeed              012
       #\Page                  014
       #\Return                015
       #\Rubout                177

Note that # \Linefeed is synonymous with # \Newline and thus is a member of standard-char. Other semi-standard characters are not members of standard-char.

KCL/AOS uses 025 (in octal) as the character code of # \Backspace.
