Purpose
Closes files that are logically closed but physically open
Syntax
CLEAR PROGRAM
See Also
Description
The CLEAR PROGRAM closes files that are logically closed but physically open because of the SET FCACHE ON command. SET FCACHE ON speeds up program execution by leaving files physically open, thereby eliminating the involvement of the operating system when re-opening a file.
Normally this command should not be needed as files should be removed from the open file cache when an open request conflicts with the file's current status, for example shared versus exclusive or update versus read-only.
Example
// Program to tidy up on exit of an application clear program
Products
Recital Database Server, Recital Mirage Server, Recital Terminal Developer
