How do you randomize pictures?

Initially I wanted to randomize strings... but I don't think it's possible. This is actually for a multiple question, but I can do the button wait procedure or something so I'll let the user click on the answer.

You do randomized pictures the same way you do randomized strings.

first, store all the possibilities in an array:
Turing:


var myPics : array 1 .. 10 of int

myPics(1) := Pic.FileNew("mypic.jpg")
...
myPics(10) := Pic.FileNew("myPic10.jpg")


Then generate a random number to decide what picture to display:

Turing:

var tmp : int := Rand.Int(1,10)
Pic.Draw(myPics(tmp),x,y,picMode)


The same can be done with strings by changing the array into a string and replacing Pic.Draw with put.

You would have to store all previous numbers in an array, then when you pick a number, check the array to make sure it hasn't been picked before. Alternatively, you could take your array of pictures and do a bunch of random swapping to mix the order up, then use a for loop to display them from 1 to 10

No, because I have no idea what you mean by that. Care to elaborate?
