1. after posting the topic here I've got 501 error with red PRISM STOPPED text in my browser everywhere ... on Lumia 950 windows phone, iPhone, Android on my Samsung Note #, Macbook pro with Catalina 10.15.1 and laptop with Insider's Win 10 build 19013.vb_release ;)
2. Microsoft has officially "killed" all Windows versions before 10 version and declared the death of win 10 too. their new name for their OS was not defined still. They said maybe Lite OS maybe 10X may be" xyz that knows" (the russian slang expression)
3. the only one feature of DQL for DOS is discussed here and I am using AI abbreviation for that feature. You can choose it by pressing F9 while making query in the DQL editor. this feature enables semantic aid (not syntax only) to user when constructing DQL for DOS. The pressing of space bar in QBE mode and QBE itself are not AI on my personal opinion (I have AI certificate from IBM Canada btw) . AI feature of DQL development has a miserable embrional form, but it is AI nevertheless. P-code made (made via half code, not in C language) microscopic AI feature of DQL is great!
4 as to any graphic environment=graphic user interface I never seen something like AI feature of DQL for DOS. users have to click on everywhere ... MS Access is the striking example and paradigm of this shitty solution under graphic interface in any "windowed" environment including all forms of X (macOS X, linuX and etc.)
5. yup, history says Gupta had a partner programmer to develop DEDOS ... everybody can see that name in Google search. But Gupta died due to car accident when driving His bicycle ... that was happened in times when DataEase paradigm "What to do but not how to do" was just changed with Bill Gates and MS approach seen in their Acces ="..if you want to do something you have to have professional programmers for that."
9. finally, the discussion is about Windows history not DataEase. plz look the 1st post of the topic. windows is nightmare and Windows 10 Insiders preview rally shows that clearly. My Catalina OS for macBook pro experience shows no problems while Internet is full of messages about Mac equipment crashed after installing Catalina and updating it ;) that is not falsification too. it is my own experience. I am pure Algebraist ... my Teacher who was student and professor at Sorbonna Ecole Normal, Paris before WWII ...and I've got strong algebraic and mathematical logic knowledge from my Teacher. Also I've got the fundamentals of Computers and those are ..Algebra and the theory of finite automat. That is why all software and hardware is good for me and works excellent ;) for I can program it without any OS in machine codes directly )))))))))))))))))))) without any Assemler, linker and etc. Also I can dissassemble manually ))))))))))))
10.Finally, I want the only one thing in DE 9 ..that semantic level aid while developing query ...as it was in DQL for DEDOS ..simply pressing one key ... and nothing more.
Thx a lot for reading my text
