    Hey guys,
    I have been given some work to do using Assembler and i literally understand none of it.
    I would really appreciate some help. The 2 questions I have to do are:
    1) Write a 6502 Assembler programme that takes in an upper case letter and turns it into a lower case letter. Your programme should finish if the user enters the number 0.
    2) write a 6502 Assembler Programme that counts the number of times each letter occurs in a sentence and stores that in a buffer. You may presume that you can hard code in the string corresponding to the sentence and the string will be null terminated and entirely upper case. The buffer should be of size 26 (for each letter of the alphabet) and should store the amount of each letter in the corresponding position in the buffer (i.e the number of A's in the sentence should be stored in position zero of the buffer and the number of S's should be stored in position 18)
    Thanks a lot
    Elanna
