fine, I have seen a lot of instruction on your marvellous web page.

But I don't understand the result I got. Lets show an example.

a=dist(20)
h=histogram(a)
print,max(a),max(h)
14.1421 56

u=uniq(a,sort(a))
help,u,h
U LONG = Array[61]
H LONG = Array[15]

Why could be h higher as a?
Why doesn't I got a vector length of 61 as uniq tells?

More and more I believe the first question does not describe what I want. .
