3. <
string
> defined using no quotes.
All strings using this format must start with an alphabetic character (A
through Z, a through z). All other characters must be either alphabetic,
digit (0 through 9) or the ‘_’ character. Any other character will delimit
the string.
Some examples are shown below:

A.2
Definition of <number>
The IEEE 488.2 standard defines four different types of numeric data. The
2835-C recognizes all four types as <number>, thus any format may be used.
1. <
number
> defined as floating point.
2. <
number
> defined as binary.
3. <
number
> defined as octal.
4. <
number
> defined as hexadecimal.
Where necessary, integers are converted to floating point numbers. In all
cases, a number is terminated by any of the below characters:
, ; <NL> <EOI> <SPACE>
Any non-valid characters detected in any number received are considered an
error in format, and an error condition will be generated in the system. There
are no differences between the 2835-C and IEEE-488.2 standard for number
definition.
A description of each type of <
number
> follows:
1. <number> defined as floating point.
Any of the following characters, as the first character of an ASCII sequence,
indicates that a number is being defined:
+ - . 0 1 2 3 4 5 6 7 8 9
A floating point number is defined as follows:
