The IDLitReader::GetFilename function method is called by the system to retrieve the current filename associated with this reader. Due to the automated nature of the file reader system, filenames can be associated with a file reader and then read at a later time. This method allows direct access to the file currently associated with the reader.
In addition, this methodology is helpful when multiple reads are performed from a given file.
Result = Obj->[IDLitReader::]GetFilename()
Returns a string containing the current file name associated with this reader, or an empty string if no filename has been associated.
