What I have in mind is using Lazarus/FreePascal forms as purely presentation layer, not for Pascal programs alone, but any language, DWScript, Python, bash, Basic, whatever even DWScript In effect the form opens a web server or another type socket where the business layer sends the screen drawing commands to. Whereas a browser is pull system, this is a both pull and push When I did some Googling, knockout.js a framework that came up, something similar for Lazarus is what I have in mind. FreePascal, LCL, fpGUI etc are the system I know and the best foundation for a high performance cross platform presentation layer that I can think of. I think parsing QML or a reasonable subset for building Lazarus UIs as an alternative to .lfm and .dfm files is where the future of the Lazarus/FreePascal lies. I wouldn't say the future, but it is area where the Pascal development ecosystem can experience a revival. It is rapidly loosing ground to programming languages which can be are interpreted, JITed, compiled, and have garbage collection, not just in usage, but in performance as well. I think my vision warrants a separate blog post.

From my ValEdit test suite:

begin
ValEd.Strings.Clear;
Valed.Strings.Add('MyYesNoRO=No');
with ValEd.ItemProps['MyYesNoRO'] do
begin
KeyDesc := 'MyYesNo: PickList';

GEM was presented by Digital Research, Microsoft had nothing to do with it. At least it was the first desktop I saw in our company on an IBM-PC. It came very close to my Atari desktop, but turned out to be crippled to allow only for 4 windows, and more crap. I may be misleaded in so far, as it might be presented by DRI even on an PC? [I only saw it running on one of our desktops] I'm not sure what GEM has to do with multitasking. You said that they were technically similar, which isn't the case. Multitasking was an example of a major technical difference they had. As the acronym GEM says, it's a Graphical Environment Manager, which e.g. on my Atari ST was installed on top of TOS.

Every platform has its own ABI and object file format, which must be supported by every compiler for that platform. See also the --target etc. switches of FPC.

There some notes about Windows 1.0 and Windows 2.0 in Raymond Chen's the old new thing blog, but i can't find specifics right now. Windows 3.0 turned out to be the first released and usable desktop version for our portable PCs (from GRiD). At that time we also used a (beta) version of the Borland C development system on Win3.0, which became our new development environment after GW-Basic. I also assisted in the development of an Atari version of BC, and there I wrote a window library that allowed (to some degree) to run Windows code on GEM. From that experiment I remember some of the fundamental differences between GEM and Windows.
