DialogProlog

DialogProlog
is an option for Dialog which can give an expression to evaluate before the dialog starts.
  • You must use a delayed rule of the form DialogProlog:>expr to prevent expr from evaluating prematurely.
  • Expressions given by DialogProlog are evaluated after symbol values are localized, and before any expression given as the argument of Dialog is evaluated.
