This code:
> bb(i) = mean(B(i:i+200))
is incorrect because you are averaging 201 points, not 100 points. Also, the variable I increases by 100 every step, so you only put valid data in B[] every 100th point.

If you are going to do it with a loop, then keep track of input array and output array separately, like this.

i = 0L
j = 0L
while i LT (n-100) do begin
bb(j) = mean(b(i:i+99))
i = i + 100 ;; Advance to next block in B
j = j + 1 ;; Advance to next position in BB
endwhile
n_output = j
print, bb(0:n_output-1)
