ASCII character conversion

The ASCII character set has nothing inherently to do with the T language or its implementations. Internally, any implementation is free to use any convenient encoding for characters, for example, a modified ASCII (such as that of the Lisp Machine), or EBCDIC. However, the language does provide conversions between characters and ASCII codes (CHAR->ASCII and ASCII->CHAR), so this correspondence is, for the purposes of those routines, a part of the language definition. The table below is also provided as a general reference, because people using T are also likely to be using computers, and this information may often be useful in that context.
