Hi Thanks to all the people who emailed suggestions to me. I was told that the problem was that I should be using huge instead of far pointers. With huge instead of far I was able to write to 64k sections of data instead of just one byte under 32k that I was getting with far. I can only think that I am not able to write to the full 262k array because IDL is allocating it in memory in some strange way that my DLL can't write to. I've had to work around it by dividing the 262k array into four sections, it seems to work without any problem. I've been told that under Win32 and Chicago etc.. all this near far and huge stuff will be a thing of the past - having done a bit of C under Unix and OS2, where it never was a thing, I can't wait. However I am stuck now because the code I'll writing is specifically for a PC running windows ( capturing images off a video camera), and although I haven't tried it, I'm sure that our version of IDL won't run in a Win32 environment. Thanks again, Don't you just love windows when it holds you down, Mark
