Managing Money With Your IBM PC by A. Glazer This disk contains all the BASIC programs contained in my book Managing Money With Your IBM PC (Prentice-Hall, 1985). Among other things, the programs can determine the after-tax cost of a loan, demonstrate the advantages of an Individual Retirement Account, compare loans which have different interest rates and different origination fees, and calculate the amount of monthly savings necessary to finance a college education. You can be confident that the algorithms used are correct: the author holds a Ph.D. in economics from Yale University and is a professor of economics at the University of California; the New York Times recommended the book in its September 29, 1985 issue. You can get complete documentation for the programs by borrowing or buying the book; it explains all the programs, contains chapters on programming and business mathematics, provides 52 extensions to the programs, and discusses 106 worked out examples. I think you can learn quite a bit about personal finance and programming by reading the book. Maybe you'll even learn how to save thousands of dollars. Many bookstores carry the book, and all should be able to order it. A few notes on using the programs. When the program asks for a month, enter the number of that month (for example, 12 for December). Enter years with four digits, for example 1986. Do not use the percentage sign when entering an interest rate. For example, enter 11.5 for an annual interest rate of 11.5 per cent. Don't put commas inside any numbers, and don't put a dollar sign in front of any number you enter. For example, enter 10000 for ten thousand dollars. Some of the programs (such as POINTS) use the bisection method to solve equations. The computer will take a few seconds to calculate the result, so please be patient. To use the programs, enter the BASICA interpreter. Then load the program you want. For example, to use the amortization program, enter LOAD "AMORTIZE, press the Enter key, enter RUN, and press the Enter key again. The names of the programs (without the .BAS suffix), and brief descriptions of them, are given below. *** Calendar programs *** DAYOFWEE Day of week on which a specified date falls DAILYODO Date that is a specified number of days away from starting date MONTHLYO Date that is a specified number of months away from starting date DATEDIST Number of years, months, and days between two dates NUMDAYS Number of days between two dates DATESINM Dates in a month on which a specified day of the week falls *** Loans *** AMORTIZE Amortization schedule for a mortgage.
