This might be handy too then, it's the official 68000 programmers manual, covering all the cpus: http://www.nxp.com/docs/en/reference-manual/M68000PRM.pdf Have fun. Cheers, Norm. -- Sent from my Android device with K-9 Mail. Please excuse my brevity. ___ QL-Users Mailing List
Re: [Ql-Users] EasyPtr and rescalable windows.
Hi Norman, I am familiar with your excellent Assembly Language book. I will take a look at the toolkit that you mention; it certainly sounds as if it could be used as a template for what I am looking for. Come to think of it, I have actually never written any assembly language on the QL, as far as I remember. The last time I attempted to write assembly, it was 68000 code on an Atari ST. The ST went up into the attic in the early 90s (it is still there), so it must have been before that. D. PS. Thanks for the great EasyPtr tutorial too.

Re: [Ql-Users] EasyPtr and rescalable windows.
Evening Daniel, Re assembly language and writing extensions, my eBook has a few chapters on that. Help yourself to http://qdosmsq.dunbar-it.co.uk/downloads/QLToday/QL_Assembly.pdf. If you need to return two values, or four, then take a look at the DJTOOLKIT sources at https://github.com/SinclairQL/DJToolkit, you will be interested in the MAX_CON function which is passed a channel I'd and 4 integers, and returns an error code as the result, plus updates the 4 integers with the channel's window or console sizes and positions: ** * error = MAX_CON #channel, x%, y%, xo%, yo% => returns an error and *updates the 4 (non-channel) parameters to be the *maximum sizes & positions that a CON channel is. ** You could write something similar quite easily, I'm sure. HTH Cheers, Norm. -- Sent from my Android device with K-9 Mail. Please excuse my brevity. ___ QL-Users Mailing List
Re: [Ql-Users] EasyPtr and rescalable windows.
Hi François, Thanks for the pointer to Dilwyn's tutorial. It is helpful but it doesn't contain what I was looking for. I did eventually find the answer here: http://www.qlforum.co.uk/viewtopic.php?f=3=1027 The solution involves PEEKing the window definition table, which is effective, but not exactly obvious, at least if you've become unaccustomed to 1980s programming conventions. I have never written a Basic extension - it's a very long time since I last attempted to write something in assembler, but this seems like a prime candidate for my first attempt, assuming it doesn't already exist somewhere.

Hi all, I am trying to get my head around EasyPtr (again). I have been playing with the new ability to create resizable windows. This turns out to be not terribly difficult, and I was able to create a resizable version of the calculator from Norman Dunbar's tutorial without suffering too much. However, creating a freely resizable version of QBase is dependent on being able to read the size of the newly resized window.and its components.
