    Smile Encrypting still

    Sorry, me again. I've gotten some really good adivice which I'm saving. But I'm still not much closer to my goal. So I'm hitting my problem from a different angle this time. If I have a set of input numbers such as 1234, how do I turn those numbers into charaters? Then with them being charaters, how would I grab just one out of the 4?. Once I can retreave the 1 charater, I should be able to return the charater to a number, add my encrypting number, then reintroduce the number into the pack.


    Thanks for the help you guys,

    function atoi() [atol() or strtol() ] convert a string to int [long].
    and _itoa() or sprintf(StringBuffer,"%d",Integer) covert int to a string.
