{{PageDescription}}
|
|
* A file must be closed when changing to another file mode.
|
|
* [[CLOSE]] files when they are no longer needed, in order to save memory.
|
|
* Files cannot be opened in the same [[OPEN]] mode using another number until the first one is closed.
|
|
* Use holding variables for each file number returned by [[FREEFILE]] so that the file reference is known.
|
|
* Will not return an error if a filenumber is already closed or was never opened. It does not verify that a file was closed.
|
|
* [[CLEAR]] can be used to close all open files.
