following each print string, so, again, it is not necessary to include it
here.
How Messages are Processed
The GPIB-MAC processes a programmin g message on a line-by-
line basis. The GPIB-MAC buffers the entire message, interprets
the function name and arguments, then executes the message.

cmd are
sent directly to the GPIB.
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 may 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
boldface in the
shown in
of the function descriptions.
