3-6. STRING
A string refers to a string of characters enclosed within a pair of
special (non-alphanumeric) characters used as delimiters. Delimiters may
be any of these special (non-alphanumeric) characters except apostrophes
('), commas (,), semicolons (;), periods (.), parentheses, and slashes
(/). It is recommended that #, +, -, and = should not be used as string
delimiters when advanced commands such as BEGIN, END, WHILE, OR, or NOT
are used. A null string is represented by two consecutive delimiters,
for example, "".
NOTE Whenever a character is used as a delimiter, it is important that
it does not appear in the string.
Nonprinting characters can appear outside the string, if represented by
their decimal numeric equivalent (in ASCII code) and preceded by
apostrophes ('). Thus the string "EDIT/3000" '13 '10 represents the
charac- ters EDIT/3000, a carriage retum (13), and linefeed (10). ASCII
characters and their decimal representa- tions are shown in Appendix B.
NOTE Blanks beyond the last non-blank character in a line are not
recognized as part of a string.
