newbie and coding help needed - railwayman - 01-23-2019 08:36 PM Hi guys, Nice to be here. I am an engineer and PhD student from Manchester UK, having fun with DM42. I had 42s few years ago but I sold it and cannot regret it. However, hope to hve good fun here. I am playing with coding. I am about the make pixel drawing program which I called D.raw With DM42 capablitities to print to image, it could be interesting. For now I have a cursor/pointer, which I can move around. I would like to use keys "PUT" to put pixel and "DEL" to delete pixel from particular location. But I have no idea how to do that. I am playing with flags 34 and 35 but does not work. So I need your help.
