CLOSE
Abbreviation: CL <SHIFT+O>
TYPE: I/O Statement
FORMAT: CLOSE <file number>
Action: This statement shuts off any data file or channel to
a device. The file number is the same as when the file or device
was OPENed (see OPEN statement).
When working with storage devices like cassette tape and disks,
the CLOSE operation stores any incomplete buffers to the device.
When this is not performed, the file will be incomplete on the
tape and unreadable on the disk. The CLOSE operation isn't as
necessary with other devices, but it does free up memory for other
files. See your external device manual for more details.
EXAMPLES of CLOSE Statement:
10 CLOSE 1
20 CLOSE X
30 CLOSE 9*(1+J)
