Function to return the last modification date of a file
The FDATE() function returns, from the operating system, the date that the specified file <expC> was last modified. The search will be carried out in the current directory and any directories specified with the SET PATH TO command. The character expression <expC> may include the full pathname, but no 'wild card' characters. The FDATE() function returns the date in the format as specified by the SET CENTURY, SET DATE, and SET MARK commands. If the file specified by <expC> is open, the FDATE() function returns the last modification date since the last time the file was closed.
