Example

print(address) 2.600000e+01
io functions
Use the io commands when you need to manipulate file input or output with
Series 3700 instruments. These commands open and close file descriptors and
perform basic I/O operations on a pair of default files, one input and one output.
io.close()
Function
Closes the specified file.
Usage
io.close(file)
file: A file descriptor to flush and close
Remarks
This command is equivalent to file:close() (on page 9-10).
io.flush()
Function
Flush the buffered data for the current output file.
Usage
io.flush()
Remarks
Use this command to flush data written to the current default file by file:write()
(on page 9-11) or io.write() (on page 9-14). Using this command removes the
need to close a file after writing to it and allows it to be left open to write more data.
Data may be lost if the file is not closed or flushed before an application ends. To
prevent the loss of data if there is going to be a time delay before more data is written
when you want to keep file open and not close it, flush the file after writing to it.
io.input()
Function
Assigns a previously opened file, or opens a new file, as the default input file.
Usage
io.input(filein)
fileout = io.input()
filein: A file descriptor to assign or the path of a file to open as the default input file.
The path may be absolute or relative to the current working directory. This parameter
is optional; if absent, the command returns the absolute path to the current default
input file (fileout).
fileout: The absolute path to the default input file.
Remarks
Any error encountered is logged to the error queue.
The remotely-accessible version of this command does not accept a file descriptor
parameter.
