PC RIM
	This set of 3 diskettes contains a full relational DBMS which is
based on the public domain RIM-5 DBMS written several years ago, and on 
which the distribution restrictions have just expired. It was translated
to MS Fortran by Glenn Everhart for general use and somewhat enhanced for
use on PCDOS/MSDOS.
	The program will run in a 512K PC, XT, or AT; it is not clear how
much less memory is enough. A hard disk is a practical necessity.
	Complete sources are presented so you can add to it, use its' B-tree
code (BT*.FOR), or whatever else desired. It may need polishing. It is to
be compiled with MS Fortran 3.3. The .EXE supplied will run with or without
an 8087 or 80287.
	This is basically a mainframe class DBMS and is presented completely
free and clear to all. Its code is fairly portable and should port to almost
any Fortran machine with little effort. It has been tested and is in heavy use
in some places.

	While you may use or give PC-RIM away, please send a donation of
$20.00 to Glenn Everhart, 409 High St., Mt. Holly NJ 08060 to support
further translations and enhancements if you use and approve of the program
and the effort of making it generally available.

	The program has been slightly enhanced so that it accepts input in
both cases (" terminates translation to uppercase) and so that }dos-command
fires off "dos-command" in an EXECed subprocess without exiting RIM.

	The following are the files on the 3 volumes. Note that they are in
Archive format. The ARC utility and its document are included so that you
can get back the original files. The library file was too big to fit on a
floppy, so it was omitted. It will have to be rebuilt by compiling the
supplied sources. The batch file is included in the source archive for doing
so. When you compile the sources to get the library, you have a programmable
interface to PC RIM from Fortran. This is documented in the manual and allows
you to add your own front ends or use the DBMS utility routines in your own
applications.
   Note that you should read the document for ARC and that it also is
user-supported software, so you are asked for a donation from System
Enhancement Associates for its use also.

	To use: (Assuming your default is drive C:)
0. Get the manual:
  Copy/b A:PCRIMDOC.ARC
  ARC -X PCRIMDOC.ARC *.*
  DEL PCRIMDOC.ARC
1. Read the manual (please!)

2. Put PCRIM.EXE onto a disk directory.
3. Extract the help database:
  copy/b A:HELPDB.ARC
  ARC -X HELPDB.ARC *.*
  DEL HELPDB.ARC
4. Just type PCRIM to fire the system up. Note that RIM must be
able to access HELPDB1, HELPDB2, and HELPDB3 for the HELP command
to work. HELP RIM is a "top level" help command.
  A "path extender" can be used to allow this without having to
work in the PCRIM directory all the time. Many such are available
from public domain sources.
