character /pet'skee/ PET ASCII. The variation (many

would say perversion) of the ASCII character set used by the

Commodore Business Machines' PET series of personalcomputers and the later Commodore 64, Commodore 16, and

Commodore 128 computers. The PETSCII set used left-arrow

and up-arrow (as in old-style ASCII) instead of underscore and

caret, placed the unshifted alphabet at positions 65--90, put

the shifted alphabet at positions 193--218, and added graphiccharacters.
