Home2Buy
Home2Buy will compute a variety of financial facts concerning purchasing a 2nd (vacation) home.
Home2Buy has a variety of features, including:
- accounts for mortgage interest and proprety tax income tax deductions,
- incorporates rental income and expenses, including depreciation
- returns from saving your money, rather then buying a property,
- appreciated value of the property
Thus, in addition to the price of the property, there are a number of other parameters that you can adjust — such as the interest rate, the per-week rent, the apprectiation rate, and your marginal tax rate.

Clique Optimization (CLOPT) — Construct/display hierarchical trees.
"CLOPT is a clustering approach that takes proximity data as input and constructs a hierarchical tree. These trees are parsimonious in that they have far fewer than the n-1 levels of HCS methods. Additionally, simulations also indicate that CLOPT is robust in terms of recovering structure from data."

Filter Designer — High-lowpass filter calculator.
"This application is a filter designer for OS/2 2.1. The user chooses what filter response they want for their filter (lowpass or highpass), what filter approximation they would like (Butterworth or Chebyshev), and what corner frequency they would like. Pressing the 'Evaluate' button gives the component values necessary for the circuit.
The filter is fourth-order, made of two second-order filters in series. These filters are in Sallen-and-Key configuration and have unity gain."

GNU Octave — a high-level language for numerical computations.
"GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. GNU Octave is normally used through its interactive interface (CLI and GUI), but it can also be used to write non-interactive programs. The GNU Octave language is quite similar to Matlab so that most programs are easily portable."

- if necessary, edit geometry: i.e. define layers, insert a map title, add a scale of miles, north arrow ...
- read attribute data as dBase-III/IV-files.
- Join geometry and topical data using a numerical key (ID).
- Select/combine one of the following data-display options:
- Choroplethe-Map
- Charts
- scaled Symbols.
- Edit legend and map title
- Print (Printer, Plotter, OS/2-Metafile)

Each plot comes with a simple but functional Graphical User Interface (GUI), which allows users to zoom in or pan to areas of interest on the plot, or to toggle between 2D and 3D plots. The plots may then be sent directly to a grayscale or color PostScript printer for hard-copy output."

PMLnCalc — A simple calculus utility.
"PMLnCalc is a simple calculus program. It was realized to evaluate expressions typed in the Input Line and to show the result in the Output Line. It uses the clipboard to exchange data with other programs (imports expressions and exports results).
The opportunity to register a special key to resume the program from within any other application while PMLnCalc is running minimized and to minimize again it simply copying the evaluation result in the clipboard makes the interaction very easy."

PMTravel — Calculates travel times at different speeds.
"PMTravel is a combination of two programs which calculate travel times for either miles or km. at different speeds. The reason that I wrote these programs is to show people how ridiculous it is to drive the 10 miles to work at 80 m/h when it only saves 1 minute, 43 seconds over driving at the much safer speed of 65 m/h, and if you get pulled over for speeding, how much time (and money) you'll spend for that 00:01:43. Albeit, driving fast for long periods of time can significantly reduce your driving time, but I think that most people that I see are just driving around the city on the freeways, and the time savings vs danger ratio is not worth it."

Bicycle Ride Calorie Calculator
"Bicycle Ride Calorie Calculator is an OS/2 PM program that calculates the number of calories expended on a bicycle ride. It provides a good estimate of the number of calories burned based on time, distance, rider weight, wind speed and direction, drafting, and climbing. It is not meant to be a completely accurate calculator and playing with the input values will reveal that the equations break down for very small and very large average speed values. Calorie expediture values seem very reasonable for average speeds between 5 and 30 mph."

ICalc is very simple, and was written in a couple of hours while I was trying to learn how to use YACC. Some of the code was stolen from HTML-Ed, and some was stolen from another project of mine, so I don't have too much time invested in it. So, I've decided to make it freeware.
