[Closed] create new window dialog with its UI elements

fn CollectDialogfn =
      (
       rollout CollectDialog "Collect" width:421 height:200
       (
        ...
       on CollectDialog close do
        -- continue somehow the cicle
       )
      )
  
  
     for i in files do 
     (
         duplicateimageRoll= CollectDialogfn
         createDialog duplicateimageRoll
     -- stop somehow the cicle
     )

Please, help! I don’t know how to do that! Should I use while and to use a key? I just don’t like while function. Is it possible to use if instead?

createDialog duplicateimageRoll modal:true
