File.CloseFile(FileHandleVariable);Description
The CloseFile closes the current file and releases any resources associated with the current file. In the case of a FileWriteHandle, the file will be saved before closing. The use of CloseFile is optional. An OTX runtime system shall automatically close any open FileHandles at the end of a diagnostic session, saving the file in case of a FileWriteHandle.
If a diagnostic sequence uses a FileHandle after it has been closed by a CloseFile action, the runtime system shall throw an otx:InvalidReferenceException.
