INSTALLATION 

The  United Nations Groundwater Software for Windows (GWW) requires 14 MB 
of hard disk space  and several additional  MB for proper operation.  
Before installing GWW, check that you have the necessary hard disk space. 

The program files in the 5 distribution diskettes come in a self extracted 
(zipped) form.  There are  small batch files on each of the distribution 
diskettes that will open  GWW and  GWWDATA  sub-directories on hard disk C 
or D and copy the unzipped files to the sub-directories.  To install the 
GWW program on  drive C, type GWW and the diskette number GWW1,  GWW2  etc. 
and press ENTER.  To install the program on drive  D,  add the letter d 
without space after the number of the GWW diskette, GWW1d, GWW2d  etc. and 
press ENTER.   Start installation with disk  1.

To print these notes, insert disk 1 in drive A or B, type PRINT and press 
ENTER.

To complete the installation, and before starting Windows and GWW, add the 
GWW sub-directory to the PATH, and add the line SET GWW=C:\GWW or 
SET GWW=D:\GWW  into the Autoexec.bat  file and reboot your computer.


ADVICE

To be able to work with the GWW program, the user must be familiar with 
Windows. The program is not completely intuitive like many other Windows 
programs.  Therefore, even a very experienced windows user will have to go 
very methodically through the entire User's Manual and often refer to the 
elaborate Help.  There are certain things that should be done and other
things that should not be done in order to  run the GWW program successfully.  
Running the program incorrectly will result in a crash of the program and 
corruption of the database.  Adhering to the instructions in the Manual and 
the Help will considerably reduce the occurrence of such mishaps.  

 
SAMPLE DATABASE

Two sample databases are included in distribution diskette 5. The first 
SAMPLE1.GWW, consists of a small number of wells but comes with elaborate 
forms and data presentation. It includes also all the ASCII files of the 
data base.

The second data base - SAMPLE2.GWW, was used for checking and proofing the 
GWW program.  Most of the data is synthetic and not from an actual case 
study. You can use this database for training. You can see on the screen 
and print most of the main features of the GWW program.  You can also 
extract and save all the ASCII files that were used and experiment with 
these simple data before you start working on your first database using 
actual field data.  

The installation batch file will install the SAMPLE1.GWW and SAMPLE2.GWW 
files in the GWWDATA sub-directory.  If you crash the program and corrupt 
the database on your hard disk,  you can reinstall the sample files by 
inserting diskette No 5 in drive A or B and type: SAMPLE C:\GWWDATA or 
SAMPLE D:\GWWDATA and press ENTER. 


UPDATE 

Small modifications, improvements and corrections were introduced to the 
GWW program after the completion of the manual. 

1. You may specify fonts (family, size, and type) for labels for well 
numbers on lithological cross sections and fence diagrams. The option to 
modify the default font is placed in Customization (on the Main Menu), 
under Well Log display parameters. The same font family, point size and 
pattern (bold/normal) is used on Fence Diagrams.

2. In the Schoeller diagram in Chemical application (Chemistry/Samples)
you cannot type 0 for the minimum value in Schoeller's range.  You will be
warned that the minimum must be greater than 0; and also the
maximum must be greater than minimum.

3. In the Well Log application, the program now calculates the vertical 
scale in such a way that whichever reporting form you use, the page will 
be completely filled.
   
4. When attempting to type data in the Concentration Time application 
outside of the currently specified Working Time Interval, a warning will 
be issued if a date outside the currently selected Time Interval is used. 

5.  In Fence Diagram application, the area for legend does not appear 
immediately. It will appear together with the first feature added to the 
legend: text, scale or lithology.
