Close a low level file

Use FCLOSE(<filehandle>) to close the file and save your changes. This will return .T. if the file can be closed successfully and .F. if it cannot.

The CLOSE ALL command will close all low level files.

A file handle is essential for these low level functions and it is usual to hold it in a local variable. You must close the file before this variable goes out of scope. Once the file has been opened (or created) it will remain open and locked to other users until it is closed.

The file will remain open even if the variable holding its handle has been overwritten or released. If you wait until you have lost the value of the handle then you will not be able to use FCLOSE to close that specific file.
