Turbo Pascal v7.0

The program is an implementation in Turbo Pascal v7.0, of an algorithm for creating a calendar. The algorithm is really a typical implementation that provides stable and reliable results, even in special cases (leap year, etcetera).

The program creates and displays on the screen custom made text in graphics mode. For the creation of the text graphics routines were used in combination with imaging routines, giving the final result presented. In old-fashioned games this was the only way to build any graphics mode symbols. Much later the method was substituted for the “Enlarged Pixels” method, which offered better visual results on the not-so-high in processing power video cards of the time.

This program converts Celsius temperature degrees to the equivalent Fahrenheit degrees. This is a simple in its implementation algorithm, indicative of how to use Turbo Pascal v7.0 to solve such kind of problems.

Despite its title, this program is not only about displaying a few characters on the screen. It is a relatively functional game (ARCADE) of the old times that can be easily expanded by adding so more functionality where needed (such as: a better camera, random graphics to substitute ASCII characters, and/or opponent spacecrafts).

The program is a computer implementation of a “knowledge–based” puzzle as those available in most crossword magazines.

The program is another computer implementation of a “knowledge–based” game as those available in crossword magazines.

This program demonstrates the usage of “Bubble Sort”-like sorting algorithms. The reason why this program is presented independently of the “File Manager” program is to emphasize on the fact that Sorting Algorithms were first developed independently of any other application. The present program can easily be expanded or modified to implement other sorting algorithms.

This program demonstrates ways to use the “Selection Sort” sorting method. The program can easily be expanded or modified to implement other sorting algorithms.

The program is a simple implementation of an algorithm for calculating a number raised to a power. The interesting feature of the algorithm is its ability to provide a good excuse for studying “Integer Overflow", through the limitations provided by Turbo Pascal v7.0.

The program is a simple implementation of a “Micro-calculator” with menu management. Includes only the basic arithmetic operations, but can easily be extended to include other more complex ones.
