Read this file for installation procedure and other information.






/* -------------------------------------------------------------------- */
This disc contains archived versions of the LETS software version 0.66
The files are: 

README         - this file
INSTALME.EXE   - executable archive (contains full version of nLETS 0.66)





/* -------------------------------------------------------------------- */
nLETS is freeware, which means you may freely use the program to assess 
whether it is useful to the needs of your LETSystem. 



To install:

1. Log onto hard disc (or high density floppy).


2. Create and move into a new subdirectory (eg. C:\LETS). This will become the 
        default directory.


3. Insert floppy into disc drive and invoke the program with:

        A:INSTALME

           Extracting then occurs...


4. To start the program type  
        NLETS




/* -------------------------------------------------------------------- */
When INSTALME is unarchived, the resulting files include:


DICTA.DBF       Data dictionary file that contains the info needed to 
                build a new set of files.
CODES.DBF       Code file with details of services

ACCOUNTS.FRM    FRM files needed for some reports
LEDGER.FRM      "
JOURNAL.FRM     "



        Extra files:

UPDATE.LET      Program development details
LETSHELP.DBF    Help files
LETSHELP.DBT    "
*.DOC           Some technical documentation


Other files (mainly *.MEM) will be created by nLETS. These are primarily for 
system configuration.



nLETS will work with the standard LETS file structures (ie. those from 
Landsman, Canada based on the dBase3 version.) However, provision has been 
made in DICTA.DBF and in the program to deal with slightly larger phone and 
postcode fields and with decimal fields in many of the accounting fields. If 
you are using the original files, then by running the Rejig Files option the 
program will alter the file structures to the newer one, without destroying 
any data that you may have. 

It would be wise to backup your data files first... 



/* -------------------------------------------------------------------- */
If you are reinstalling the software and you already have a set of data files 
then you should reinstall to a new subdirectory. Follow the above procedure to 
install the new software, but choose a new subdirectory eg. c:\NEWLETS


1.  You will then need to copy over your previous data files. These are stored 
in the DBF files in your old subdirectory. Assuming that your old subdirectory 
is c:\LETS then the DOS command to copy the files over is: 

        copy c:\lets\*.dbf


2.  Reinvoke the program with the command

        nlets d

This will rebuild the files properly.


3.  Finally, you MUST reindex the files. This reestablishes order.






/* -------------------------------------------------------------------- */
nLETS is designed to run on a PC with DOS 3.30 (or more), 640K RAM and a hard 
disc with at least 1MB free space. 512K RAM is not sufficient. Colour graphics 
are nice to have. 


It is important to check that your computer system has the capability of 
handling all the files that nLETS requires. To do this ensure that the 
CONFIG.SYS file includes 2 lines with something like: 

        files = 36
        buffers = 12





/* -------------------------------------------------------------------- */
nLETS takes command line options that affect the way that the program works. 
These are: 


        0   - Administrator level - total access plus an override on the 
              monthly update which normally insists on a printer being online.
              Rejig data files.
        1   - Administrator level - total access to whole system (Default)
        2   - Data level - no access to monthly or Update routines.
        3   - User level - no adding, editing or deleting options available

        D   - Create a new copy of DICTA.DBF in root directory


The default level is 1


The 3 levels (Admin, Data & User) are a way where people could use the program 
in different ways. Although the administrator will need full access to the 
system, other users will differ. For example, it would not be wise to let a 
casual user have access to the Monthend routines. Batch files could be set up 
that invoke nLETS at different levels, and people could be assigned to the 
appropriate batch file.

The following command line options are stored for future use.

        H   - use Hewlett-Packard mode for inkjet or Laser printing
        E   - use Epson mode for dot matrix printing

        C   - forces a Colour mode
        M   - forces Monochrome mode (useful for portables)
