October 1, 1979 FORMATTING SPECIAL CHARACTERS
RESTRICTIONS ____________
• Overprinting is restricted to a single special character.
• No character may overprint itself (thus no boldface).
• A character represented by a format code cannot be overprinted
with another character represented by a format code. Thus, the
special character representation of a backspace (!22) cannot be
used in conjuction with another special character code (i.e., a
literal backspace must be used).
EXAMPLES ________
• In the examples below, "$" represents a literal backspace.
input: "b!22/"
b yields: "/"
input: !193 - !194
yields: A - B
input: !173!139(a+b) * c!155 + d!189 = f
yields: [{(a+b) * c} + d] = f
input: !173*24!189
yields: [24]
