Heres the scenario.
Im makin that rpg i talked about earlier and I have an option where the player can write to a file to "save" his/her game. The problem is that it saves as a tesxt file which can be EASILY hacked and so i want some sort of thing to encode the variables being saved (this is to ensure that when i make a stand alone program ppl will not cheat).
The thing is, i've got strings figured out (quite easy to do) but how could i do it w/ numbers other than adding a certain number to the value?
Any help appreciated.

well... you could use a mathematical method of Matrix Encoding... but unless you've taken Grade 12 or OAC finite math... I doubt you know how to do it... plus, it might be a bit odd making the code, but I could probably do it for you... maybe...
What if you apply a mathematical formula to it? Say 3X20=Y when you encode it. Then to decode it it's just X=(Y+20)/3
Alternatively; maybe you can write an algorithm to convert the text to letters using the chr(X) function. So each number would output to the .txt by Y=chr(X), then reading it back in, you can use X=ord(Y). ord returns the number equivilent of the character.
It's still possible someone could write a program to do that though... lol, if I did write that matrix encoding, I can almost guarantee you no one would break it (unless they manage to decode the .exe and found the encoding matrix)
