About the applications on this page.
All downloads on this side are provided free of charge and without any warranty of any kind. You may use them as you like, but if you do so, it's entirely on your own risk! Please, have a look at this Web site's disclaimer for further details.
The programs on this page are text-based (non-graphical) programs, running in a console, such as MS Windows Command Prompt. The executables on this site have been compiled for a Windows 64bit platform. The sources of most of them should be suitable without greater modifications to create binaries for Windows 32bit, Linux, Mac OS and even FreeDOS. Just recompile them on the platform where you want to execute them. If you just want to run the program, use the icon in the Exec column to download the executable (if it needs supplementary files such as data, these are normally packed with the executable in the .zip download archive). If you are interested in the code or want to recompile the program (to adapt it to your needs or to use it on a different platform), use the icon in the Source column (the download file will be a .zip archive with all relevant files, NOT including any executables). To view the description of the program (including Lazarus/Free Pascal features and screenshots), click the program name in the Program column.
