Rand.Int Command and Subtracting Arrays

-----------------------------------

Uh could some explain how the Rand.Int command works? I have looked at the helped and tried it out myself but it says that the variable is of the wrong type. I am making a sort of trivia game and was wondering if, when a user answers a question correctly, how can i subtract that question out of the loop so it won't appear again? Thanks for the help.

Rand.Int() works by taking two parameters, the lower number and the higher number (limits).  Since it is a function, you have to "do" something with it, like outputting it or assigning it to a variable.  You are most likely getting "wrong variable type" because you are not using an int to store the randomized number, ie:
var randomNumber : int := Rand.Int (1, 10)
will generate a random number from 1 to 10.

As for deleting questions, look up arrays and store all the unanswered (or answered, your choice) questions in it.[/code]
