How Messages are Processed
The GPIB-232CT processes each programming message on a line-by-line
basis. The GPIB-232CT buffers the entire message, interprets the function
name and arguments, then executes the message.
Function Names
The function names have been selected to indicate each function's purpose,
thereby making your programs easy to understand. However, if you wish
to reduce some overhead in your program and do not mind giving up these
advantages, you can use only as much of the function name as is necessary
to distinguish it from other functions. This abbreviated form of the function
name is shown in
boldface
in the function tables and in the syntax portions
of the function descriptions.
Function Argument Delimiters
When you type in a function, separate the first argument from the function
name with at least one space. Separate each additional argument with at
least one space or comma.
In the syntax portions of the function descriptions in Chapter 8, the square
brackets (
[]
) that enclose some arguments indicate that those arguments
are optional. Do not enter the brackets as part of your arguments.
Abbreviation for Argument
The term
bool
is an abbreviation used for an argument in the function
descriptions. The value for
bool
is: 1 = true, on, or enable; or 0 = false,
off, or disable.
