	[307,20] - USGS library contributions:

MDINIT.COR	RMDEMO (V3.2) correction files for the correct display of
MDPAGE.COR	IN: and OUT: tasks in systems with a resident task loader
REMAP.COR	and display of UP time in RSX-11M systems (conditionalized.
RMDDEF.COR	for R$$EIS, but not tested on a non-EIS machine.)

UFD.COR		Correction file to allow a non-privileged user to create
		UFDs with the same group number as the protection UIC.

TIMER.FTN	FORTRAN execution profiler subroutine and test driver.
TIMERTEST.FTN	(See upcoming Multi-Tasker article.)

GETCMD.MAC	FORTRAN access to system indirect command file processing.

CSI.MAC		FORTRAN access to system CSI parsing routines, including
CSISV.MAC	construction of switch tables and switch value tables.
CSISW.MAC

STOP.MAC	Replacement FORTRAN STOP statement processor that eliminates
		STOP message.  (See December 1979 Multi-Tasker article.)

TCLOSE.MAC	FORTRAN callable file close with truncation (after flushing
		the file buffers via a forced .POINT).

TTYATA.MAC	FORTRAN link to TT driver unsolicited input character AST
ASTTST.FTN	mechanism (via completion routines) and test driver.
		(See April 1979 Multi-Tasker article.)

USERMAC.MAC	USGS macro library sources and the library itself. The source
USERMAC.MLB	file may be of interest to MACRO programmers who would like
		macros for simple terminal I/O, ala FORTRAN TYPEs and ACCEPTs.
		The source file is heavily laced with comments.

	The rest of the files belong to the programs below:

CRASH		Used to force a system crash from a privileged terminal.
		(See March 1980 Multi-Tasker article.)

CWD and PWD	Change Working Directory and Print Working Directory.
		Combination of ASN ddnn:=SY: and SET /UIC=[g,m] in one
		command with lots of extras, e.g., warns you if the UFD
		does not exits, prints disk usage (blocks and percent).
		Type CWD /HE and PWD /HE for help.

DAMMIT		Cute messages (taken from old DECUS tape and converted for 11M).

IDX		FORTRAN IV/FORTRAN IV-PLUS cross reference generator.
		A substantial enhancement to the old IDX program that
		processes all FOR and F4P keywords (including INCLUDEs)
		and generates the correct line numbers for each compiler
		(with proper carriage control for appending to the
		compiler listing file).  See IDX.DOC and README.IDX for help.

PRINT		11M-PLUS style print command for the old print symbiont;
		accepts optional /DElete switch.  Type PRI /HE for help.

SNAP		Snap dumps (almost) any running task by faking out PMD...
		into thinking the task asked for it.  Accepts all the
		arguments available in the SNAP$ macro.  Allows non-
		privileged users to dump their own tasks only.  Type
		SNA /HE for help.  (Try snapping PMD... sometime!)

SQUISH		Compresses imported text files by removing text beyond a
		specified column and trims trailing blanks and tabs.  See
		SQUISH.TXT for help.

UNDELETE	Very dangerous program for recovering files accidentally
		deleted from a disk.  Allows file specifications similar
		to SRD Select Entry patterns.  Written to recover a system
		disk that had been completely (accidentally) wild card
		deleted (it works fine).  For system programmers only.
		See UNDELETE.DOC for help.

WHO		Who is on the system (with names taken from the account file)
		and currently executing tasks with their status.  Also allows
		query of account file info, such as WHO BAKER or WHO 100,1.
		(Makes only one pass through ATL and account file.)  Type
		WHO /HE for help.

Command files are available for each program by name (except PWD, which is
really CWD installed as ...PWD), and there is a blanket command file,
USGS.CMD, that will build the necessary libraries and all supplied tasks.

If you choose to build each task manually, be sure to invoke @USGSLIB first
to build the common libraries.

The following files should be available for a build of all tasks:

		LB:[1,1]EXEMC.MLB
		LB:[1,24]MCR.OLB
		LB:[1,54]RSX11M.STB
		LB:[200,200]RSXMC.MAC

P.S.  This tape was assembled at 3 a.m. after the machine's power supply
      was repaired from a failure earlier in the evening.  We have tested
      the command files individually, but did not have time to test them
      all together.  They should work in any UFD on your disk.  Good luck.
