 	// This is not at all the tightest possible regexp for MVS LIST
	// output, but I'm not a mainframe guru so I have little idea what the
	// range of valid values are.  I just needed to get the filename (Dsname);
	// note that no other FTPFile fields can be filled in with the results of
	// a LIST on MVS.  The 'Referred' date seems to be 'last accessed date'
	// and not 'last modified date' so I didn't bother parsing it.
	//
	// Of course it works perfectly as-is and it distinguishes header lines from
	// file results so that's the important thing.  
	//
	// This parser should be used when SYST returns:
	// 'MVS is the operating system of this server. FTP Server is running on z/OS.'
	//
	// Also note that there is no concept of directories in MVS, just datasets,
	// which have names composed of four dot separated names of up to 8 chars.
	// As a result, FTPFile.FILE_TYPE is always used. -JN 6/2004 jnadler<at>srcginc<dotcom>
