Commodore PET - BASIC Statements; Close

BASIC STATEMENTS
CLOSE
The CLOSE statement closes a logical file.
Format:
CLOSE file
where:
file
is the logical file number that was given
when the file was opened.
Each file should be ciosed when Vou are through accessing it. Since the PET
allows only ten files to be open at a time. it is good practice to close files as soon
as they are not in use to allow other files to be opened. A logical file may be
closed only once between file open commands. Ail open files must be closed
before a program
END.

The particular operations performed in response to a CLOSE statement de-
pend on the physical device and the type of operation for
which the file was
opened. For
PET cassette tapes. closing a file after reading it will stop the PET
from reading the file any further. Closing a file after writing to it is critical: the PET
puts an end-of-file mark at that point. an end-of-tape mark for write code 2. and
finishes writing the last of the buffer contents onto tape.
