Mod is used in another language, as said in its manual:

The mod operator returns the remainder obtained by dividing its operands. In other words, x mod y = x - (x div y) * y.

Can anyone show me how this is done in PB? I'm trying to convert RC4 encryption from another language to PureBasic.

mod in PB is the operator '%' , use like this: '10 % 2'..

Use %.

E.g. 5 % 3 will equal 2.

Awesome, Thanks, One last question, i have no clues for this, But what is '^' in PureBasic?

For example

Chr(Asc(Mid(Str$,i+1,i+2)) ^ k)

Pow(5, 2) would return 25, or 5 raised to the 2nd power.

Lol, awesome.. Slow-pokes. Thanks for the help, this may be going off topic now, HOPEFULLY the last question, But whats wrong with:

BoxRC4(i) = BoxRC4(j)

The error is:

Array Index out of bounds.

What would be the reason causing this?

assuming that "BoxRC4" is a Array either "i" or "j" are outside the specified Range
Ex:

Dim BoxRC4(10)

BoxRC4(10) = BoxRC4(11) ;<- 11 is error 10 is ok

check your loops

Either i or j has a value outside of the array dimensions.

Eg:

Dim Arr(10)

Arr(99) = Arr(2763)

Do a Debug i and a Debug j just before the assignment to see what the values are.
