Syntax and Definitions
A.1 Definition of
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 parameter is required.
1. , using double quotes. “this is a string”
2. , using single quotes. ‘this is a string’
3. , using no quotes. thisisastring
A description of each type of follows:
1. defined using double quotes.
A double quote indicates that a string follows, and the string is terminated
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 (ascii decimal 13), (ascii
decimal 10), or End or Identify characters.
2. 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 (ascii decimal 13), (ascii
decimal 10), or End or Identify characters.
