8.2.1.2. Command Syntax
Commands are not case-sensitive and all arguments within one command (i.e. ID
numbers, buttonwords, data values, etc.) must be separated with a space character.
All Commands follow the syntax:
X [ID] COMMAND <CR>
Where
X is the command type (one letter) that defines the type of command.
Allowed designators are listed in Table 8-2 and Appendix A-6.
[ID] is the ma
chine identification number (Section0). Example: the
Comm
and “? 700” follo
wed by a carriage return would print the list of
available commands for the revision of software currently installed in
the instrument assigned ID Number 700.
COMMAND is the command designator: This string is the name of the command
being issued (LIST, ABORT, NAME, EXIT, etc.). Some commands may
have additional arguments that define how the command is to be
executed. Press ? <CR> or refer to Appendix A-6 for a list of available
command designators.
<CR> is a carriage return. All commands must be terminated by a carriage
return (usually achieved by pressing the ENTER button on a computer).

8.2.1.3. Data Types
Data types consist of integers, hexadecimal integers, floating-point numbers, Boolean
expressions and text strings.
Integer data are used to indicate integral quantities such as a number of records, a filter
length, etc.
They consist of an optional plus or minus sign, followed by one or more digits.
For example, +1, -12, 123 are all valid integers.
Hexadecimal integer data are used for the same purposes as integers.
They consist of the two characters “0x,” followed by one or more hexadecimal digits
(0-9, A-F, a-f), which is the ‘C’ programming language convention.
No plus or minus sign is permitted.
For example, 0x1, 0x12, 0x1234abcd are all valid hexadecimal integers.
