DialogSymbols
DialogSymbols is an option for Dialog which gives a list of symbols whose values should be localized in the dialog.
DialogSymbols :> x, y, ... specifies that x, y, ... should have local values for the duration of the dialog.
DialogSymbols :> x = , ... defines initial values for variables.
In addition to any symbols you specify, Dialog always uses local values for $Epilog, $Line and $MessageList.
The DialogSymbols option sets up local values in a dialog in the same way that a Block enclosing the dialog would.
See Section 2.14.2.
