Classic "bucket" or "pigeon hole" application.
For ANSI strings:
DIm arr(32 to 255) 'assumes only printable values
for x = 1 to len(strTest)
y = aSC(mid$(strTest,x,1)
arr(y) = arr(y) + 1
next
for x = 32 to 255
if arr(x) > 0 then debug.print chr$(x) & " - " & str$(arr(x))
next
If it's a Wide String that can contain any Unicode point, then you really need to use a more
complex solution such as a BTree or a Collection where you check whether you already
have an item with a key matching the current character code and either add it or increment
its value.
