Appendix A
Syntax
and
Definitions
The IEEE 488.2 standard defines two types of string data. These strings are
either single or double quoted. For convenience, the 2832-C also recognizes
an unquoted string with certain restrictions as detailed below. Any of these
forms may be used where a <string> parameter
is
required.
1. <string>, using double quotes.
"this is
a
string"
2. <string>, using single quotes.
'this is
a
string'
3. <string>, using no quotes.

A description of each type of <string> follows:
1. <string> defined using double quotes.
A double quote indicates that a string follows, and the string
is
termi-
nated by another double quote. A double quote may be embedded
within the string by using two double quotes together:
Example: "this string contains a
""
double quote"
All characters within the two outer double quotes are considered part
of the string.
It
is
an error
if
the string does not terminate with a double
quote. The string cannot contain the <CR>(ascii decimal 13), <LF>(ascii
decimal lo), or End or ldentify characters.
2.
<string> defined using single quotes.
This form
is
similar to double quoted string. A single quote indicates
that a string follows, and the string is terminated by another single
quote. A single quote may be embedded within the string by using two
single quotes together:
Example: 'this string contains a
"
single quote'
All characters within the two outer single quotes are considered part of
the string.
It
is
an error if the string does not terminate with a single
quote. The string cannot contain the <CR>(ascii decimal 13), <LF>(ascii
decimal lo), or End or ldentify characters.
