Note:   FINFO returns the value of a system-dependent information item for an external file. FINFO returns a blank if the value given for info-item is invalid.

This program assigns a fileref using the FILENAME function, opens the external file and determines the amount of information available about the file.

The information available on files depends on the operating environment. Some host companions contain a table describing the information available.
