     ' This function returns a value read from an INI file
     '
     ' Arguments:
     ' myFilePath  [string]  the (path and) file name of the INI file
     ' mySection   [string]  the section in the INI file to be searched
     ' myKey       [string]  the key whose value is to be returned
     '
     ' Returns:
     ' the [string] value for the specified key in the specified section
     '
     ' CAVEAT:     Will return a space if key exists but value is blank
