perlman@wivax.UUCP (Gary Perlman) (12/13/84)
I've received so many requests for information about my
public domain stat package, I thought I would give it a
plug for everyone looking for free software. This is not
your everyday offer for junnk that won't compile and when
it does, you don't want it anyways. These are great
programs. I won't post the code to net.sources. You can
only get it on tape from me. All the details you need
follow, so please read carefully.

UNIX|STAT
COMPACT DATA ANALYSIS PROGRAMS
UNIX|STAT is a set of UNIX System data manipulation and
analysis programs developed at the University of California, San
Diego by Gary Perlman (now teaching at the Wang Institute of Gra-
duate Studies). The programs are designed with the UNIX System
philosophy that individual programs should be designed as tools
that do one task well and produce output suitable for input via
pipes to other programs. Interactive use is supported in the
UNIX System shell which also provides a programming language for
complex analyses. Typical usage involves a pipeline of transfor-
mations of data followed by input to an analysis program, summar-
ized schematically by:
INPUT DATA | TRANSFORM | ANALYSIS | OUTPUT RESULTS
Functionality often built into statistical packages (e.g., graph-
ics, sorting and other data manipulation) is not re-invented in
UNIX|STAT which delegates such responsibility to standard UNIX
System tools.
FEATURES
easy to use (negligible training period)
simple input formats (free format field oriented)
used in pipelines with other UNIX System utilities (sort, vi)
flexible data manipulation
data validation provided (range and type checking)
full documentation support (manual entries, tutorials)
extensible (many modular C functions)
faster than most packages (usually < second/analysis)
small enough for micros (10-25K byte programs)
runs on any UNIX System (V6, V7, 2.8BSD, 4BSD, III.0, System V)
public domain software
in use at > 300 UNIX System sites for four years
DATA TRANSFORMATION PROGRAMS
abut abut data files
dm column oriented data manipulator
io control and monitor input and output
maketrix create matrix type file from free-form file
perm randomly permute lines in a file
repeat repeat a pattern or file
reverse reverse lines and characters

UNIX|STAT is Public Domain
The programs have been released to the public and are dis-
tributed to anyone who wants them. Persons wanting to get a copy
of the package should contact me directly. You can get the pack-
age for free if you send me a tape and a prepaid return mailer.
Otherwise, a distribution fee is charged to cover the costs of a
tape and mailing ($20.00 U.S.). Checks should be made out to me
personally. Documentation for the package is available free of
charge.
The distribution includes:
The C source files for all the programs.
The documentation source files.
A collection of test examples.
