the other function Encode as i understand it work like this
we have string called :code1 BYTE “JMARTYVWBDLQNCXGZEKIPUFOHS”
and we have other string called:code2 BYTE “abcdefghijklmnopqrstuvwxyz”
it converts the letters between two arrays using indexces.for example
if the letter is M it is in index 1 ,it will converts it to b coz it is also at index 1
if the letter is not found in code1 ,it will stay like it
This function i didn't how to write it .any hits?any helps?
and can u help me a bout the main function
i am waiting for ur reply
