I divided all applications into two groups according to for what operating system were created. The first group covers programs for Windows and the other group represents programs for operating system MS-DOS.
Applications designed for Windows
These programs are among of all the latest and they are created in development system Borland Delphi. None of these programs writes anything into the system register or system directory of Windows. If you will want to uninstall some program, you can just remove its folder from your hard drive.
Applications designed for MS-DOS
I created my first programs in Q-Basic (Editor Basic, Duch Pampuch, Tajná mise) and sometimes later in Pascal (Minové pole, Piškvorky). There are primary designed for operating system MS-DOS, but there are running even under Windows without troubles. Q-Basic programs are consist of source codes (*.bas files), because I didn't keep at disposition a compiler. All the people who know this development system can modify these applications as necessary. I would like to call attention that all programs are freeware, so you can ignore a notification about that the dispersion introduced software is punishable and strictly forbidden, which it shows after running. All the five programs are available in Czech language only.
