File I/O
You can use the file I/O commands to open and close directories and files, write data, or to read a file
on an installed USB flash drive. File I/O commands are organized into two groups:
•
Commands that reside in the
fs
and
io
table, for example:
io.open()
,
io.close()
,
io.input()
, and
io.output()
. Use these commands to manage file system directories; open
and close file descriptors; and perform basic I/O operations on a pair of default files (one input
and one output).
•
Commands that reside in the file descriptors (for example:
fileVar
:seek()
,
fileVar
:write()
, and
fileVar
:read()
) operate exclusively on the file with which they are
associated.
The root folder of the USB flash drive has the absolute path:
"/usb1/"
You can use either the slash (
/
) or backslash (
\
) as a directory separator. However, the backslash is
also used as an escape character, so if you use it as a directory separator, you will generally need to
use a double backslash (
\\
) when you are creating scripts or sending commands to the instrument.
For basic information about navigation and directory listing of files on a flash drive, see
File descriptor commands for file I/O use a colon (
:
) to separate the command parts rather than a
period (
.
), like the
io
commands.
