For example, the wait function may be called using either of the

Function Argument Delimiters
When you type in a function, separate the argument from the
function name with at least one space. Separate each additional
argument with at least one space or a comma.
In the syntax portions of the function descriptions in Section Four
the square brackets
are optional. If you want to include optional
information, you do not need to type the brackets, only the
information inside the brackets.
Abbreviations for Arguments
The function descriptions in Section Four use abbreviations for
some arguments. They are as follows:
addr a GPIB address
one or more
a boolean value: 1 = true, on, or enable
0 = false, off, or disable
GPIB Address
Each device on the GPIB has a GPIB address. The GPIB-MAC’s
address is 0 at power on and may be changed using the
function. Refer to the manuals of your GPIB devices to learn their
addresses. You will need to know these when you begin to
program the GPIB-MAC.
Only the lower five bits of each GPIB address are significant. These
bits may be in the range from 0 through 30 for both the primary and
the secondary address. For example, the binary value 01100010
(decimal 98) is interpreted as decimal 2.
