APPENDIX C - LENA CONFIGURATION
===============================
If your copy of the LENA Program Set was obtained through a BBS,
please do a virus check if your BBS does not have an automatic virus
scan. For safekeeping, make a copy of the Program Set on a floppy.
Note: Mailed LENA Program Sets are free of any known viruses.
You must run LENACFG.EXE first. LENACFG creates the necessary
LENA.CFG file required by either LENAS or LENAN; neither will run
without it. LENACFG only creates the LENA.CFG file, reads but does
not alter any existing computer data.
The LENA Program Set you receive should _not_ have LENA.CFG in it. If
one exists, the program set may be corrupt.
LENA screen displays are in color and that color requires ANSI.SYS to
be in your DOS and stated in your CONFIG.SYS file as:
DEVICE=C:\DOS\ANSI.SYS
~~~~~\
(path may be different in your system)
If that statement is not in your CONFIG.SYS file, add it using any
ASCII character text editor. [EDIT with MS-DOS 5.0 or later, EDLIN
with 3.3]
Run LENACFG and answer the questions. If you are in doubt whether or
not your computer system has a numeric coprocessor, LENACFG will
prompt you to run CPUID. CPUID is a small, public-domain file written
by Intel Corporation to identify the CPU and numeric coprocessor (if
any).
LENA makes extensive use of the computer calender-clock to
'time-stamp' all outputs. Such time-stamping can be invaluable in
later review of LENA analysis-solutions. If your computer's calendar-
clock isn't working, the programs will run anyway, but you will have
to write little memos to yourself to tell you when a particular
solution was made.
LENACFG will create the .CFG file and exit, prompting you to rename
either LENAS.EXE or LENAN.EXE to 'LENA.EXE.' LENAS.EXE is the
'Standard' version of LENA, compiled with software numeric routines;
LENAN.EXE is the 'Numeric' version, compiled with inline calls to an
80x87 numeric coprocessor. LENAS runs on any computer having an 80x86
CPU but LENAN will "hang" on a computer not equipped with a numeric
coprocessor. Keep LENA.EXE and LENA.CFG in the _same_ directory; LENA
will refuse to run if LENA.CFG is in a different directory.
If you would like to keep the LENAMAIN.HLP and LENACKT.HLP files for
on-line reference, please copy them to the same directory as LENA.EXE
and LENA.CFG. Data files may be kept in another drive:\directory as
desired.

File sizes and minimum contiguous free RAM is as follows:
File Size, bytes Free RAM Size, bytes
Standard CPU, no coprocessor 97,346 (95K) 142,655 (139K)
Numeric coprocessor 89,332 (87K) 135,775 (133K)
HARDCOPY
All hardcopy outputs expect a standard printer capability of '10
Pitch' character spacing (ten characters per inch horizontal) and 6
lines per inch vertical spacing. ASCII character set only. Form-
feeds are not output in LENA or in any text file in the LENA Program
Set.
VIDEO DISPLAY
Any standard display device will work with the LENA Program Set, color
or monochrome, CRT or LCD, no difference on Video Cards. CONFIG.SYS
file in root directory should have a Device statement for ANSI.SYS to
see color.
MOUSE
There is no Mouse control in the LENA Program Set. All commands and
data are direct alphanumeric entries.
BAT FILES FOR CONVENIENCE
If you plan on using LENA often, it is convenient to make a .BAT file
for the Root Directory having just two lines:
CD <driveletter>:\<directory(s)>
LENA
If you have more than one physical or logical drive, a .BAT file in
the root can access LENA directly by a three-line .BAT:
<driveletter>:
CD <directory>
LENA
Any ASCII text editor can create a .BAT file.
With either in the root directory, you can run them from any other
directory. The batch file itself can be named LENA.BAT or whatever is
convenient for you.
Note: A "Root Directory" is that specified by an AUTOEXEC.BAT 'SET
PATH' statement. If your AUTOEXEC batch file has a statement of:
SET PATH=<otherdrives:\directories>;C:\
---
the 'C:\' (underlined, note back-slant) indicates it is the Root.
