population := 0

open file

character := read-character

while not end of file

    if character is letter then

      convert character to upper case

      position := find(letters, character)

     if position = - 1 then

       letters[population] := character

       counts[population] := 1

       add 1 to population

   else

       add 1 to counts[position]

end if
