Modifications to RSX11M V4.1
		_____________________________

	Changes to V4.1 are far less than V4.0.  As DEC has adopted some
of our ideas, we are switching over, where ever possible, to their way
of doing things.  Very few changes have been made from the V4.0 release.
Those made either are to support KMS account or because the overwhelming
convenience of having them outweighs the support costs.

MCR CHANGES
-----------

MCRDIS

  The enclosed version of MCRDIS.SLP probably will not work without 
modificataion.  MCRDIS has been changed again at DEC to include some
of the features in the SLP patch (I think).  Look the patch over.  The
patches just relating to the PIN procedure interpreter (#) and the patch
relating to the counting of the times indirect is used should go in.
The only question is whether or not DEC is going to allow all commands which
MCR doesn't fine to get passed to ...CA.  Jim Kauffman (DEC) says this will
be the case, but the MCRDIS for which the SLP file was written, does not
have this feature.

Two changes are made in MCRDIS. The first modification is to facilitate the
use of the procedure interpreter, ie make it as easy to use as INDIRECT. Since
'@' stands for indirect execution and interpretation of a command file, '#' is
taken to mean 'direct' execution(no fancy interpretation) of the command file.
Hence the command '#CMDFIL' will issue a 'PIN CMDFIL'. The second change
incrememts a counter in a user's UCB each time @ is run. This change is
conditionalized on KMS Accounting enhancements being present. 

MCRDEF.SLP,SPSOV.SLP, ST1OV.SLP, ST2OV.SLP

	These SLP files implement the SET /LIBUIC and SET /TIMEOUT commands
for MCR.  They are also conditionalized to include the KMS special features
which allow non-privileged users with certain privilege levels to change 
login uics within or across groups.

ICP
---

	Modifications (very small) are made to some modules of
the indirect command file processor to enable /-LI (/LI is default mode),
set substitution as the default and to add a <ERRSEQ> special symbol so
the user can read the current error sequence counter if error logging
is active.

ICPFIL		This is modified by the addition of the switch "LI".


ICPPRE		Sets ICP to initial state of ENABLING LOWERCASE, 
		SUBSTITUTION,AND GLOBAL.

ICPROT		Add comment.

ICPSYT		Add special symbol <ERRSEQ> to provide access for
		error logger error sequence number.  Nice to have access
		to this if doing tape backups.  Or if mount causes error
		which must be reset.

INS
---

INSFL	Allows RUN $ to look on both LIBUIC, NETUIC and SYSUIC.

INSHD	This module also contains the code required to assign run
	run privleges on a user by user basis.  Increments U.INCT if KMS
	Accounting running.
