General notes on using program CASH FLOW................. The program
requires Lotus 1-2-3 version 2.01 in order to run. IT WILL NOT RUN
ON THE OLD VERSION 1A......Documentation by R. J. Lockett
************************************************************************
START-UP:
1. Place your Lotus ver. 2.01 disk in drive A and type "LOTUS" and
press <RETURN>. When the main menu appears press <RETURN>, as
cursor will be over "123". Follow Lotus prompts until the spread
sheet borders appear.
2. For one floppy machines - remove the Lotus disk and insert the
"Cash Flow" disk.
3. Type /F<RETURN> (three keystrokes) to see the Files list. The
cursor should be over the only file displayed "CASHFLOW.Wk1".
4. Press <RETURN> to load the file. You should now see the first
page of documentation. Use the <PgUp> <PgDn> keys to scroll
between the three pages of documentation. READ THEM THOROUGHLY.
5. To start the program press <Alt> & <D> simultaneously. At the
top of your screen you will see the main menu.
DATA INPUT:
1. All data is entered through menus which are generally self
explained. By moving the cursor left or right with the "arrow"
keys to the menu choices, you can see the description below each
prior to making a choice. Once the choice has been made position
the cursor over it and press <RETURN>.
2. Generally, the first step is selecting "Input" on the main menu.
A sub-menu will appear and starting with "Rates" you will move
through each selected topic until all required data is entered.
Always make sure you have returned each time to the right submenu.
Selecting "Quit" on the sub-menu the program will return to the
main menu.
3. Production rates can be input as daily, monthly, or yearly. The
program automatically calculates the yearly rates if entered as
daily or monthly. After selecting one of the above, you must
choose one of the three options:
a) Oil - calc by decline, w/gas calc by entering GOR
b) Gas - calc by decline, w/oil calc by entering Yield(B/MM)
c) Typed - oil & gas rates typed in manually by year
page 2
4. Items a) and b) above have the option of two decline methods:
constant rate or exponential. Move the cursor to selected method
and press <RETURN>. Then you will be asked for the decline rate
and the first year rate of production. Be sure and enter the
proper rate that corresponds to your first selection of DAILY,
MONTHLY, or YEARLY. The program calc the data, enters it in the
proper cells, and returns to the sub-menu for your next selection.
5. Item c),"TYPED", permits you to enter the oil and gas rates in by
typing from the keyboard. Be sure the rates correspond to units
selected initially, ie, daily, monthly, yearly.
*** NOTE: After selecting "TYPED" the menu will disappear from
the command line at the top. This is because when you
type in data it will appear here before entering a cell
in order to make any corrections. DO NOT USE <RETURN>
to enter the data in the worksheet. Instead, use the
arrow keys (left,right, up, down) after typing the data
to the command line and to move to the next position.
If you have a color monitor the variables that will
change are high-lighted in green. Also the <End> and
<Home> keys will permit you to see the top and bottom
limits of the data range quickly and to review the data
for final error check. Using these two keys as well as
the arrow keys, will not jump you out of this range and
get you lost. To exit this range and return to the sub
menu, just press <RETURN> regardless where the cursor
is. Be sure no data exists in the columns from an old
run below the new data. If it does, "zero" it out
prior to exiting. These notes apply only to the <TYPED>
option.
6. "Prices" and "Expenses" can be constant or escalated by the in-
flation factor. The inflation factor is found in the sub-menu
option of <OTHER> of the <INPUT> option of the main menu.
Also this data can entered manually using the <TYPED> option.
7. If a drilling prospect is being evaluated the program allows for
dry hole investment as well as dry hole risk and completion risk
factors.
EXECUTION:
1. Once the data has been entered and checked, return to the main
menu for the next option. If the production rates were entered
by the decline curve option, the <LIMIT> option should be pressed
in order to eliminate any unprofitable years from the worksheet.
2. Next press <CALCULATE> if the project has no backin interests. If
a backin interest exists press <FARMIN>. When the program has
finished computing, a summary table will be displayed on the
screen.
3. To print the results press <SUMMARY> then <FOUR> which will be
four pages of the economic projection. If the input data is
desired press <BACKUP>. Select each option when printer stops.

HELPFUL HINTS:
1. A knowledge of Lotus 1-2-3 will make life a lot eaiser using this
program. However, do not despair. Get into the program and try
experimenting with the menus. Do not be afraid of messing up the
program or data. it is always on file on the floppy disk and you
can start over by retrieving the file again. Before trying to
enter your data, proceed through each option of the menus and
observe the old data and the range limits of the worksheet.
2. When finished NEVER SAVE YOUR FILE USING THE ORIGINAL FILE NAME
"CASHFLOW". After pressing </> <FILE> <SAVE> enter a new file
name prior to pressing <RETURN>. The extension ".Wk1" is not
required as Lotus will attach it.
3. If you do get lost and the sub-menu is still on the command line
keep pressing <Q> (QUIT) and the program will back up to previous
menus all the way to the main menu. If the sub-menu disappears
and you are hung in an option range just press <Alt> and <D> at
the same time and the main menu will appear on the command line.
4. Remember, <Alt> and <D> will not work if a menu is present on the
command line.
5. One last word of confidence - make a copy of your cashflow disk
before starting.
