Then welcome to this century of programming ;) Do you want to work a GUI or a console application? If the former then you should take a look at the OnKeyPress/-Up/-Down events of the various GUI components. For a console application you should look at the Mouse and Keyboard units which abstract mouse and keyboard access in a platform independent way. Using assembler to access keyboard and mouse is not possible on any modern OS.

Re: [Lazarus] key press in graphics
Hi Jim, it is not clear to me if you want to write a windows application or a console application. In the 1st case, you mostly use the OnKeyDown/OnKeyUp and OnMouseMove/OnMouseDown/OnMouseUp events of the form. For the 2nd case, you could find useful infos here (originally for Delphi): http://stackoverflow.com/questions/5845080/how-i-can-implement-a-iskeypressed-function-in-a-delphi-console-application You may find this free library helpful: http://sourceforge.net/projects/graphics32 HTH Duilio 2014/1/26 JIMB wand...@ntlworld.com: Hi, New to the group so a bit a of history..

Nowadays you can use a Form with a PaintBox for drawings, in Delphi or Lazarus.
