String handling issue with Free Pascal

[Sogcelak]

I actually needed to look up how multithreading exactly works in Pascal. And I still don't get half of it, so that will take some time. Keep in mind I've hardly ever used objects in my programs, only simple ones. This TThread class is a mess compaired to them.

I've deleted the part of the program where it writes out every try, now it just outputs the result, and it is a lot faster now. At 5 character length it still seems unexplainably slow(I haven't tried with more). This multithreading seems like something that could work but I need to study it further before I can implement it in my program.

If you would want to optimize it a bit, i would first get rid of NextChar() function. You could put all valid characters in a string constant, something like

const validstr = 'abcd....ABCD....XYZ0123456789';

Then matter of changing character is simply increasing character index by 1.

index:=1;
validstr[index] is 'a'
inc(index);
validstr[index] is now 'b'

I have a tutorial that covers the basics of multi-threading.
