It looks like I will be adding to UNIX|STAT over the next few years.
Allready, I have modified about a dozen of the programs so that
the printed documentation is not keeping up with what is on-line.

This file contains some highlights of the changes to UNIX|STAT.

This file is structured so that a date is followed by a program name
and the extent of the changes.

Tue Jan  8 19:56:25 EST 1985
ALL	plan for syntax standard changes
	I am now using the getopt command line option parser for
	many of the programs.  Eventally, all the programs will
	use it so that the command syntax is consistent and
	conforms to the Hemenway & Armitage UNIX standard.
REGRESS major changes (backed up with oldregress.c)
	Now only the first column is the predicted variable.
	Previously, all variables were predicted with all others;
	this was because it was easy, not for any good reason.
	Added functionality includes significance tests to
	see if individual variables add to the others.
	This should promote better analyses.
DATAPLOT new program
	This program is an interim replacement for the plotting
	capabilities of the PAIR program (AKA BIPLOT).  It allows
	defining more information about the axes.
COLEX	new program
	This program provides the column extraction capabilities
	of DM and is provided for systems that do not have YACC
	so that they can compile DM.  In some ways, it is superior
	to DM as a column extractor because it allows ranges of
	columns ot be specified.
MORE	new program
	This program is available on most Berkeley UNIX systems.
	This simplified version allows paging on systems that
	don't have it.

Fri Feb  1 14:25:39 EST 1985
CALC	bug fixed
	Calc used to blow up with recursive expressions like
		a = 12
		a = a + 1
	Now it checks for recursion and prints an error message.

Thu Feb  7 01:43:31 EST 1985
DM	portability enhancements and better expression printer
	DM used to assume that all data types were of size int.
	Now all sorts of non-portable casts that did not work
	on MS_DOS have been replaced by strong typing.  It should
	not affect any UNIX versions of the program.

Mon Feb 11 17:19:48 EST 1985
POF	better approximation added to reduce rounding errors.

Sat Feb 23 11:26:56 EST 1985
MAKETRIX
DESC
VINCENT
TS
	scanf was replaced by the more efficient getword.
VINCENT	added capability to read one file from stdin using "-"
PARSELINE now uses a register variable for efficiency

Wed Feb 27 18:03:47 EST 1985
MANSTAT	added -u option, clean up code
MAKETRIX	added getopt
REPEAT	changed command line options
CALC	on-line help now only available interactively

Mon Mar  4 00:42:42 EST 1985
DESC
PAIR
TS
		converted to getopt
*PLOT	removed variable width strings
CHECKIO	fixed MSDOS code
DM	new fixes for MSDOS (should now work)

Tue Mar  5 20:57:37 EST 1985
TRANSPOSE	now uses getopt with -f option for field format
	no longer reads from a file--only stdin
ABUT	now uses -f option for format of fields
PERM	no longer reads or writes files--only stdin and stdout
RANDOM	new random seed produces more random result
********************************************************
many programs now consider ignored operands an error
all programs now exit with a 0 error status on successeful runs
most programs now only read stdin and write stdout
most programs now use getopt for command line option handling
comparison of floating point values to zero have been defined in unixstat.h
program versions have all been updated to 5.0 for major new release.

Mon Apr 22 01:45:21 EST 1985
ANOVA	nreplics variable used to be (char), now (short) to avoid overflow
	version 5.1

Wed Apr 24 15:11:59 EST 1985
unixstat.h	#define	SMALL_MEM added to compile on smaller systems
	affects desc, pair, ts, perm
	version 5.1

Wed May 15 17:53:03 EDT 1985
IO had bugs when options were supplied.

Thu May 30 17:38:34 EDT 1985
SERIES	bugs when low == high fixed
