Appdrive$ + Appdir$ + "save.arr"

You should use Apppath$ instead of Appdrive$ + Appdir$.

Really? I didn't know Apppath$ existed... useful to know

really? I've always used Drive+dir and its always worked fine. /shrug

It would work fine, it's just a waste of a string concatenation..

Although Appdrive$ + Appdir$ won't make a noticable difference in speed than using Apppath$, It's an important habit to always go for the most efficient way to solve a problem. At least my experience is that people who care about those nonsense-issues become much better programmers than those who think "The difference is so small that nobody will notice, so I don't have to care!".

All the small differences mount up and you end up with a slow application.

Just like the saying 'every penny counts'.

I've been able to save files just by doing Appdir$ + "arr.txt" for example. Any reason why I should do that differently? It saves it in the directory of the app.
