PROGRAM DOCUMENTATION BANK MANAGER I hope that some of you like to save money or do some business and dream about the big fortune like I do. The program I send is aimed to help with solving mathematical problems for all the dreamers like me who wonder what to do with their 'fortunes' from summer jobs. I typed the prog in following the book '2^5 Mathematical Programs in Basic' by two Polish authors. I bought the book a few years ago and used the simple programs during my studies. Unfortunately for you it is written in Polish so I have prepared the English versions of some programs. 'Bank Manager' is based on solving an equation: P*(1+I)^N+S*(1+I*X)*((1+I)^N-1)/I+F=0 Too long? I hope not. The letters have the following meaning: P - start amount to be borrowed or lent, S - instalments, F - final amount to be paid or taken back, I - interest rate per year, N - operation time (years), X - equals 1 if paying ahead, and 0 if paying back. I hope everyone understands how he can become a millionaire. I wish you that. Even though I have had this prog for quite long there has been no miracle so far, but of course everything is possible. The program is written in Basic of course and is written in a very simple way so it can be easily used on other computers. It starts with the menu where you have to choose the problem which disturbs you and then put some data to the machine. It is very simple so I hope nobody will have any trouble with it. To help you in getting started I will give you a few examples of problems to be solved. 1. Uncle Max lent to his nephew Jimmy a small amount, £8.00 for one year. After this time nephew Jimmy returned £8.96. Was uncle Max fair? He can add interest rate only once a year as he has not got a personal computer. How big is his interest rate? Warning: If there are now instalments put 0 where necessary. 2. Now uncle Max is in poverty and he borrows £8.00 to buy a pocket calculator. His nephew Jimmy demands 12% per year. How much money has uncle Max to pay back every month to return the whole debt within a year? Jimmy is a proud owner of a pocket calculator and he adds interest rate every month. 3. After this operation both our friends decided to run a real business. They took an amount of money to the West Midlands Bank and left it for one year. They were very lucky as their interest rate was 12% per year added every month. After one year they got £901.46. How much money did they leave in the bank? 4. Uncle Max wanted to buy a flat for his nephew Jimmy. He borrowed from the bank £100,000. He will have it paid back within 30 years. He is going to pay £1,125 at the end of every month (back). After 30 years his nephew Jimmy will have to pay back another £3,580 of the debt that he has inherited. What was the banks interest year per year? 5. The flat is quite far from the nearest Tube station so nephew Jimmy decided to buy a bicycle. He is going to save money in the bank for 3 years and he will pay £1.00 at the beginning of every two weeks (ahead). As a well known customer he will have his interest rate added every day but his rate will be 5.5% per year. Will he be able to buy a bicycle after this time? I hope that now you will be able to buy lots of flats and bicycles with only £1.00 after ... some time. Piotr Pagowski, Warsaw, Poland 7 COLUMN CARD PATIENCE This is a computerised version of a very old card patience game. It takes a fair amount of skill to complete, but there is a large element of luck in how the cards have been dealt. The cards are dealt face down onto a table of seven columns, the number of cards in each column increasing from 1 to 7. The top card in each column is turned face up. The remaining cards are kept ready to be laid out. The game is played by building onto face up cards in the columns, in decending value, alternating red and black. Aces can be moved face up to the left hand side of the screen, where cards of the same suit can then be stacked on top in increasing value. The remaining cards are turned over 3 cards at a time onto a pile in the bottom left corner of the screen. Cards can be moved from this pile and built up either on the stacks or on the columns. A particular column or the pile is selected by moving the pointer to that column using the left and right arrow keys. The following keys can then be used in conjunction with the arrow keys. A - Picks up a single card or run of cards. D - Drops the picked up cards at the column selected. S - Moves the selected top card to the stacks. Pressing Space turns over the next 3 cards onto the pile. Kings may be moved to empty columns. The game is completed when all the cards are stacked face up on top of the aces. When the game was originally played with real cards, some people used to cheat slightly, but would never admit to it. For their benefit a small cheat has been included. Pressing the C key will alter the order of the cards turned over on the pile. If you get really stuck pressing the Q key will quit the game, and you will be prompted to start again. There are three files to the program; 1) PATNCE; this has all the character control codes for drawing the picture cards, and these cards are built straight into memory in the locations &1100 - &11EE. It also generates the display for the user instructions when required. 2) SCREEN; this is a file containing the title screen which has previously been drawn and saved. This is loaded straight into memory with *LOAD SCREEN 3000 from the PATNCE part of the program, to produce a MODE1 title screen. Editor's note - I have altered *LOAD SCREEN 3000 to *LOAD SCREEN FFFF3000 in order to make the program TUBE-compatible. 3) NEWPAT; this is the main part of the program which is automatically loaded with PAGE set at &1200. This program is then able to access the memory between &1100 - &11EE to print the picture cards on the screen when required. The game can be run from the normal 8-Bit menu or from a keyboard command of CHAIN"PATNCE". Try to complete the game without using the cheat, but if you do cheat, never admit to it!!
