Associate the value obtained with Manipulate to a new variable?

[alfomorosini (giacomo morosini)]

Hi,
I would like to know how to associate the value obtained with manipulate to a new variable.
For example:

Manipulate[A, {A, 1000, 5000}]   

If I choose a value of A= 2000 with manipulate, how can I use this value for a new variable,
for example

B=A

My best regards,

Jack

You can try just assigning it, like this

Manipulate[
 b = a; (*seeting new variable to a *)
 Column[{a, b}],
 {a, 1000, 5000},
 TrackedSymbols :> {a}]

Now b gets the value of a each time a is changed.
