WORDS
A word is composed of a combination of not more than 30 characters chosen from the character set
for words. The word cannot begin nor end with a hyphen. The space character is not allowed in a
word; the space is a word separator. Wherever a space is used, more than one may be used. A
word is ended by a space, or by a period, right parenthesis, comma, or semicolon followed by a
space. A space must not immediately follow a left parenthesis or a beginning quotation mark. A
space must not immediately precede a right parenthesis or an ending quotation mark except when
the space is included
in
a literal.
Words are specified by the user or they are COBOL reserved words. User-defined words include
all names assigned by the user to elements in the program; they must never be from the set of
COBOL reserved words.
Ljterals are also considered user-defined words, but they are not restricted to the limits imposed
on other words.
