Well, I preferred DOS to Windows OS :laugh: as it was so SLOOOOW! It got better by the last version.

@RickZeeland I'd like to thank you very much for that first reference.:thumbsup: There are always gems in here (I knew about Alt-F4 but not Ctrl-F4) I've been programming in FoxPro and then Visual FoxPro (the older ones may dimly remember those) as a serious hobby that ran my business for nearly 15 years, and beyond since 1985 and I'm 77 now. I tried to learn C# in 2012 but after 26 online courses (in about 5 days) it only got as far as "Hello World", and nowhere (I wasn't "here" then) could I find out the important bit - how to manipulate and store data in a database. FoxPro is 32 bit and not cloud compliant AFAIAA. I have started to read one of the links' recommended (and FREE!!) books and it promises to reveal what I need to do to achieve aforesaid data manipulation. Hopefully, in the end I might produce a cloud based, which is the future. Thanks again, onward and upward, Visual Studio 2019 here I come again. :-D

Hamiltonian Matrix + Wikipedia = Head Hurts :laugh:

Only if you have a really big fan blowing at a speed at least that of the aircrafts V2 (take off) speed. :laugh:

I am probably the most irrelevant person here as I still use Visual FoxPro (but keep reading!) I am retired but had a problem with a local council department. I asked them some questions and then wrote a simple system (maybe 40 hours coding) to obviate their problems that "there was no way round" and gave them a demo on my ancient laptop. They were open mouthed at the result and are looking to see if they can somehow get a separate laptop to install it on as "they would never allow it on their network". It should save them hours of boring paperwork per week. SO I got some satisfaction from that, although I didn't do it for money, I might get a reduction in the bills for the junior football club I am treasurer for. Alan

I recognise that look. Happens with most people. Alan

All my code is old, I am still using Visual FoxPro :laugh: it's tiny (can run it on a pen drive!) and "does what is says on the tin."

Is that not the idea behind Covid/Great Reset? Not that I disapprove as long as it's not me quite yet.
