SUMMARY

You (the developer) can require a person using your application to use design controls to exit a FoxPro screen by making the screen MODAL. To do this, use a MODAL clause on the READ command when you design the screen.

However, if you design the screen as non-MODAL, you can still give the screen a MODAL feel by adding a few lines of code as demonstrated in this article.
