/* Checks if source contains string. On success function
* returns position in source, on failure returns -1. */
native contain(const source[],const string[]);
Means that:
new A[10] = "BlahBlah"
new B[10] = "LAHLAH"
//contain(A, B) will return -1
// So if -1 != -1
if(contain(A, B)) != -1)
{
//Something will happen if A and B match.
}
