Closing a File: CLOSE Statement
Usually, any external file opened should be closed by the same program before it
completes. The CLOSE statement disconnects the unit and its external file. You
must specify the unit number (UNIT specifier) to be closed.
You can also specify:
• Whether the file should be deleted or kept (STATUS specifier)
• Error handling information (ERR and IOSTAT specifiers)
To delete a file when closing it:
• In the OPEN statement, specify the ACTION keyword (such as
ACTION='READ'). Avoid using the READONLY keyword, because a file
opened using the READONLY keyword cannot be deleted when it is
closed.
• In the CLOSE statement, specify the keyword STATUS='DELETE'.
If you opened an external file and did an inquire by unit, but do not like the
default value for the ACCESS specifier, you can close the file and then reopen it,
explicitly specifying the ACCESS desired.
There usually is no need to close preconnected units. Internal files are neither
opened nor closed.
