I am sure I would enjoy this if I knew any z80.  I'm actually doing the same thing in my Java class. Nice.

For curiosity I read about most used sorting algorithms even before classes, but now I will probably have to do it for class. So yes, it is quite fun to see quicksort in z80.

My only concern at a glance is how it keeps popping without pushing.

It uses the stack to save the elements.
A stack overflow can happen in large lists and maybe cause a slow down because it pushes and then pops a lot. But stack is efficient enough to be even used for clearing large portions of memory when speed is a must.

We need to make a list of masterpieces in TI-BASIC to put almost certainly Exodus in 1st place.

While doing some research for WikiTI I have found this: http://frank_y.scripts.mit.edu/pages/z80qsort/

Here is the code for quicksort:

I hope some z80 junkies enjoy. And discuss.

Do you think you will remain busy for the entire school year or is it just kinda temporary? I hope you can eventually return, even if not as active as you were last year.

After the first weeks, I am slowly managing my time better and eventually when I have no extraordinary worries, I hope, I can first have fun with a project and post here a bit.

Yep, I have seen interesting RTS as side scrollers. And doable in our calculators.
Have you ever played Glory Days (platform: GBA or NDS)?

Thanks for the replies.

I forgot to tell, I enjoyed very much participating Omnimaga forums in particular. It was really nice time spent here, made me laugh quite many times and learn a lot.

No worries about me, I am 100% fine, just much more occupied than ever because of University.
To the curious I followed Mathematics. (I also enjoy Engineering and Physics, it was a hard choice)

I also learnt some new skills (C and Python, easily grasped, takes experiences to master) and I might start to do some projects (web and math oriented) with new people I am meeting. Finally I find abundance of good chess players... hahaha

I will make effort to tackle my calculator projects but it will be in the long term.
Unfortunately I can only follow Revsoft forum 1 time a week or so.

See ya on the forums when I have an opportunity.

PS: sorry to not give news earlier but I was not in the mood to write until today.

My uncle liked that show and because of that I know of those Batman series.

Hilarious scene.
