many games, this is coded as a FOREVER loop, with a STOP THIS BLOCK to escape when we win or detect an inconsistency. It uses two global variables, one to count the number of guesses and the other for the buttons to tell us when they are pressed. There are more elegant ways to accomplish the latter, but they'd result in multiple WHEN I RECEIVE scripts, and we'd have to make LOW and HIGH global for those scripts to use. Also, we change the values of our input variables, which some people would consider bad style. But since those variables are local to this procedure, it really doesn't hurt anything outside this script. Students will organize their code in many different ways. It might be useful to have them flag with comments where each of the five steps (or however many steps /their/ algorithm has) is carried out.computer guesses my number from (low) to (high)

Not In ListThis will be the most common student solution. There are many other ways it could be done. For example, here's a recursive solution:EMPTY? is in the Tools library.1

1The last line says that the position of VALUE is one more than its position in the list without its first item. For example, if the DATA list is {3,4,5,6} and we want to know the position of 5, first find its position in {4,5,6} (namely, 2) and add 1 to get 3, which is the position of 5 in {3,4,5,6}.

guess22This is essentially the game program, but with the user interface parts removed. I also replaced the FOREVER loop with a REPEAT UNTIL. I think FOREVER is okay for games, but in a serious program the stopping condition for the loop should be self-documenting. (There's still an early stop if the error condition LOW>HIGH occurs. In this case it means that the supposedly sorted list given as input isn't sorted, or if the desired item isn't in the list.)

guess2This is exactly the code from the previous problem, but with REPORT instead of SAY.

LABEL will stamp text on the stage at the given font size. The direction of the text is the direction the sprite is facing, and color will match the pen color.
