RT-11 V5.5 patch for Y2k - release notes, by MOSES

The monitor and - first - the most frequently used utilities have
been updated for usage until 31-dec-2099 inclusively.

The following files have been patched so far:

	CUSTOM.TXT    15P 18-Jun-1999
	PIP   .SAV    30P 24-Jun-1999
	DIR   .SAV    20P 21-Jun-1999
	IND   .SAV    58P 16-Nov-1997
	MACRO .SAV    63P 30-Jun-1997
	LINK  .SAV    49P 18-Jan-1998
	LIBR  .SAV    24P 19-Nov-1997
	BSTRAP.MAC    96P 21-Jul-1997
	KMOVLY.MAC   233P 29-Jun-1999
	RMONFB.MAC   167P 11-Mar-2004
	RMONSJ.MAC    84P 11-Mar-2004
	SP    .MAC    88P 22-Jun-1997
	FSM   .MAC    41P 30-Sep-1999
	 14 Files, 946 Blocks

The following tools have been exempted from being patched:
	- DUP, because it doesn't clobber Y2k;
	- SYSTEM.MLB, since DEC themselves did it yet;
	- SYSLIB.OBJ, idem;
	- ERROUT, since not used so far;
	- BUP, idem (option /L [SUM 3-19 bottom, 3-20 ...]);
	- QUEMAN, since being outperformed by SPOOL (i.e. SP.MAC);
	- IND.SAV on disk AUTO, since it is special (rather, the 
		general instance IND.SAV from disk 1/8 is done);
	- further less important stuff.

Any tools else are not concerned [SUM B-1].

As orthogonal derivatives of a release chain, the patched utilities
identify themselves by a plus sign, appended to the version report
(e.g. "IND V05.28+"), when the user responded with an idle <RETURN>
to the utility prompt (*). The bootstrap routine shows an extended
boot message too.

From 1-jan-2000 on, the DATE command requires century input -
	1-jan-00 and so on is illegal then. The same applies to
	those options that deal with the year.

PIP does not implicitly propagate the protection attribute from the
input file to the output file anymore. If the user wants the output
file to be protected, (s)he must protect it explicitly - regardless
of the input file's protection status.

While DIR became Y2k-compliant for Magnetic Tape [ANSI standard
X3.27-1978 Level 4], it did not for TA-11 DECassette, since the
latter has been obsolete since RT-11 V5.6 yet. Rather, it inferes
the year-of-century numbers - as stored in the cassette's file
headers - to the years 1973. through 2072.
