************************************QREPORT************************************

	QREPORT is a disk quota report program. It reports UIC, username,
blocks used, % of base quota used, base quota and extended quota for each
valid UIC on the current default disk family (SYS$DISK).

	QREPORT was written for use with the DISKUSE utility found on the
fall 83 DECUS tape, but it can be patched to work with the normal VMS quota
scheme. 

	The username information is read from the UAF using RMS ISAM. If
multiple users have the same UIC, the first user (alphabetically) is reported
as the owner. If a UIC cannot be found in the UAF, the user name will be
printed as '????????????'.

	The report is broken up into UIC groups with the exception of the first
page, which reports those UIC's having unlimited quotas (signified on our
system by having a base quota of 999999). Group totals and grand totals are
given. Grand totals do not include the totals for the unlimited quota UIC's. 

	This program assumes that you are using the DISKUSE program found on
the Fall 1983 DECUS tape. DISKUSE treats the overdraft quota as the base quota
and treats the permanent quota as your extended quota. QREPORT labels the two
quotas as if you are using DISKUSE. You can use this program without DISKUSE
if you change the following lines;

	MOVL	DQF$L_OVERDRAFT(R11),R2	 ; ***** BASE QUOTA     *****
	MOVL	DQF$L_PERMQUOTA(R11),R5	 ; ***** EXTENDED QUOTA *****

			TO

	MOVL	DQF$L_OVERDRAFT(R11),R5	 ; ***** EXTENDED QUOTA *****
	MOVL	DQF$L_PERMQUOTA(R11),R2	 ; ***** BASE QUOTA     *****

	NOTE: Use of this program requires a system UIC, BYPASS or SYSPRV. It
 is not a good idea to install it with BYPASS or SYSPRV.

	NOTE: QREPORT has not been tested under VMS V4.0 and may not run
 because of the expanded UIC size in V4.0 and possible changes to the UAF.

	Compile and link thusly;
		@QREPORT

**********************************TREE.COM*************************************

	Tree.com is a command file which produces a directory tree of a 
 specified disk or disk family. No files or file information is given,
 only directory names.

	This command file was written to use BYPASS privilege, but SETPRV will
 also work. Under V4.0, READALL should work too. To use, type;

		@TREE diskname:
			or
		@TREE

	Omission of a disk name causes TREE to use your current default disk
 SYS$DISK. Several temporary files are created, but the final output is
 TREE.DAT in your current directory. A copy is also printed on the system
 default printer.

	Since TREE gets its information from the DIRECTORY utility, any V4
 changes could change the positioning of certain data within a print line. If
 this happens, it should be quite simple to fix the problem.

**********************************FLIPPER**************************************

	FLIPPER was designed to give a process an increased percentage of the
CPU without locking up the system. If you have a process which is compute
bound, and you increase the priority above 4, it will "hog" the system and
may force a reboot. FLIPPER runs at priority 5 and flips another jobs
priority between 4 and 5 in 1 second intervals. This gives the process a larger
percentage of the CPU while still allowing other processes to run. Up to 20
processes can be controlled at one time. When the last process terminates,
FLIPPER terminates. Note that FLIPPER is written in C.

	To run, you must first define a symbol;

		FLIP :== $disk:[dir]FLIPPER

	Then you give it the process ids;

		FLIP 3002a 5001f 70022

************************************MORE***************************************

	MORE emulates the function of the MORE utility of UNIX. It types text
much like the TYPE command, but it pauses after each screen of data. This
version is designed to work with VT52 and VT100 terminals, as it uses reverse
video and cursor positioning. Other terminals could easily be handled by
making minor changes.

	Once MORE pauses, it displays the name of the file and the percentage
of the file that has been read. This percentage is not too accurate for small
files but is still in the ballpark. At the pause, the user may type the
following commands;

		<space>		Advances 1 page (23 lines)
		<return>	Advances 1 line
		D		Advances half a page
		Q		Quits the program

	MORE does not currently handle wildcarding, but may be changed at some
future release. Other handy things which could be added are reverse and search
functions.

	You should define the following symbol;

		MORE :== $disk:[directory]MORE

	A compile/link command file "MORE.COM" is provided. Note that MORE
is written in C.
