Here are some Delphi7 examples of using wrappers to call system functions from KolibriOS.lib.
Also, it is possible to use FreePascal compiler i hope. Newer version is more compatible with Delphi.
The main goal is more convenient programming with KolibriOS API.

Tools needed:Here omf2d utility just in case:Some examples and KolibriOS.lib:It contains these 5 examples:
{1} Just a simple window.
Used functions: DrawWindow, GetScreenSize, WaitEvent, BeginDraw, EndDraw, GetKey, GetButton, ThreadTerminate.
