hello Richard
on my Mac when I double-clicked on the bbcsdl application it would not launch properly, however I copied the contents of bbcsdl to a new folder and from the terminal changed to the Resources folder and launched bbcsdl with SDLIDE.bbc as parameter and it launched ok, ran some tests and they work ok.
also tried BBCEdit but the start-up window was too small to display all the menus and when resizing the window it would not refresh the window leaving the enlarged area blank.

When you extracted the disk image file (BBCBasic.dmg) it should have created an Application (BBCBasic.app). You should definitely not be looking 'inside' that application nor attempting to execute anything called 'bbcsdl'. Instead, you should execute the BBC Basic Application itself by double-clicking on its icon.

That is neither necessary nor correct. You should treat the application bundle as an opaque entity.
Here are the installation instructions that the person who tested the app for me recommended:
Download the BBCBasic.dmg file to the Downloads folder:
Open the .dmg file (you may be asked to address the Security & Privacy option under Allow Apps):
Copy the BBCBasic app to your Application folder or the Desktop (or wherever you want it):
Double-click on the app to run it. Quote:| also tried BBCEdit but the start-up window was too small to display all the menus and when resizing the window it would not refresh the window leaving the enlarged area blank. |

Please report any problems with BBCEdit to its author Andy Parkes; contact details are in the Help menu.
Richard.

Richard, that's exactly what I did but the program segfaults, however if I launch it as I mentioned then it works.

Very strange. Perhaps you could investigate further and if possible let me know where the problem arises. As you probably know, when you double-click on an app bundle it executes the file having the same name as the bundle, in the Contents/MacOS folder.
So in this case you should be able to simulate the effect of double-clicking on the application by executing the file BBCBasic.app/Contents/MacOS/BBCBasic. This is a hard link to the file BBCBasic.app/Contents/Resources/bbcsdl. The symptom you describe would happen if the disk image file didn't properly recreate the link, but that would be a bit worrying.
Richard.

Richard, from the terminal I cd into BBCBasic.app/Contents/MacOS and then issued ./BBCBasic BBCBasic.bbc a window opened with the message "choose ide" but after a couple of seconds it segfaulted

OK. I'm not too sure why you added the BBCBasic.bbc parameter because obviously Mac OS doesn't do that. To reproduce what the OS does when you double-click on the app you should be issuing the command ./BBCBasic alone.
However I don't expect that makes any difference in practice. If I have understood what you have said so far, issuing the command ./bbcsdl in the Resources folder works, but issuing the command ./BBCBasic in the MacOS folder doesn't. But that ought to be 'impossible' because the latter is a hard link to the former, so as far as the OS is concerned you are doing exactly the same thing!
I am unavoidably having to use SDL 2.0.3 because the latest release (2.0.4) isn't available as a 32-bit Framework for Mac OS for some strange reason (it'a almost as if the SDL maintainers have forgotten that modern Macs still happily execute 32-bit applications!).

Richard I am happy that it's working on the Mac, I made a shell script to launch BBCBasic and so far all the demos work.

opengl.bbc doesn't work, but that is to be expected as it makes platform-specific SYS calls (it doesn't work on Android either).

Richard
I've tried out BBCSDL2.0 v0.14a on Windows and Mac (both latest OS), not all the files, but those I have tried work perfectly. I'm pleased to see it working on the Mac because I bought a second hand Mac Mini, which I've upgraded. It will be good to be able to use BBC Basic on it.
First impressions about the IDEs:
Looks: I prefer yours.
Working: I prefer a light background and I couldn't immediately see if the colours could be changed on Andy's IDE.
I think I will play with both of them for a while, to see which I like best.

To be fair, there's no way to get a non-white background on my IDE (other than to edit the code)! The other syntax colours can be selected, but not the editor background.

Although it works fine here, a couple of people have reported that the Win32 edition crashes in bbcsdl.bbc as a result of this statement:
Code: SYS "SDL_SetWindowSize", @hwnd%, dlg%!8 DIV 2, dlg%!12 DIV 2
The reason for the crash isn't clear, but experimentally it seems that changing the window size using VDU 23,22 instead fixes the issue:
Code: VDU 23,22,dlg%!8 DIV 2;dlg%!12 DIV 2;8,16,16,128+8
I've uploaded a new version with that change:
http://www.rtr.myzen.co.uk/bbcsdl20.zip
As far as I am aware neither the Linux nor Mac OS version is affected, so I haven't replaced those.
Richard.
