Notes Concerning Mortgage Master


Mortgage Master is written in Turbo Pascal 4.0. Unlike many PC based
calculation programs, Mortgage Master calculates all figures to 18
significance digits. This is done using a binary coded decimal
conversion routine. While this does slow down the processing, it
increases the accuracy from 11 to 18 digits and insures no rounding
errors. The entire program uses windows for display, help screens
and error notification. All options are menu driven and the program
gives options to return to the menu or end the program after each
calculation.

Financial fields are displayed with 11 digits, giving the possibility
of loans in the hundreds of millions of dollars. Some of the fields are
displayed in three, four or five decimal places.

An on-line help facility is available from the main menu. Simply
press the H key, then press Enter. Functions keys F1 thru F8 are
used for various help windows. The F9 key will return you to the
Main Menu again. The Help windows cover much of the same information
as in the general introduction above.

All Error messages do to data entry problems are displayed in a
window in the center of the screen. Simply press any key to
return to the input mode and enter the corrected data.

NOTE: A sample Amortization Schedule as prepared on your printer
is not included. The format is similar to the screen output
schedule, with four(4) years of payments being printed on
each page.
