st: RE: A dialog box to perform simulations.
No doubt you could use a dialog to do this,
but it doesn't strike me as the easiest approach.
Be aware that -display- has a very simple interactive
handle that could well be adequate here, namely
To the question how do you design an interactive
program in Stata, my answer is to design a syntax
that you want to use!
