Description
Writes the specified expression(s) to a previously opened
file, using the specified file handle.
With the help of this command, several expressions may
be printed in the same line. When the separator is a
comma (,), the subsequent expression will be written at
the next tabulator position.
When the separator is a semicolon (;), the subsequent
expression will be written directly behind the previous
one.
Notes:
•
Before
may output to a file, it needs to be
opened for output or appending first (please see the
description of the
OPEN
command and the
OUTPUT
and
APPEND
modes in this subsection). If you try to write to a
file that was not opened before, a runtime error will
occur.

With the help of the

print data to the 4400’s screen. Please refer to subsection
•
also reads data from the SCPI system. Please
