How do I store a number in Labview?

[JeffC]

This is a simple question so please bear with me.
I have a control where I can enter a number. I then push a button and
this number should be stored. When the user enters a new value and
again pushes the button, the store value is updated with the sum of the
first and second values entered.

Do I need to use a while loop with a shift register to implement this or
is there a better way? Thanks.

Hi Jeff,

      It sounds to me like a while-loop w/shift-register is the way to go.
