Just a simple question. When looking up Trap Tasks in the help file, Trap task #12 is different in the sense that it gives you an option to turn off the keyboard "echo". But it doesn't explain what an "echo" is.

My questions are:

  1. What is a keyboard echo
  2. What application would this trap task be used for?

Keyboard echo means that when the user is providing input via the keyboard, the characters that he/she types will be displayed as they are typed (they are echoed).

The application of that trap task would be if you don't want the input to be echoed. If you have no such use-case in your program then you simply don't need that trap task.
