Finally, it is often useful to ask the user for a small amount of information before proceding.

The simplest way to ask is to pop up a text window and ask the user to submit a response. This can be done using class FillInTheBlank:

	FillInTheBlank request: 'What is your name?' initialAnswer: 'Jean'

Often, instead of requiring a user to type in a text response, it is possible to let them choose from all possible alternatives in a menu. There are many varieties of menus in Squeak; one of the simplest is the PopUpMenu, which is used as below:

 menu :=
		labelArray: #(
		lines: #(3 6 8).

	menu startUpWithCaption: 'Pick a color' 6
