Although you can change the loop’s control variable in the body of the loop, we highly recommend that you don’t! Check out this program:
For N = 1 To 10
TextWindow.WriteLine("Inside loop: N = " + N)
N = N + 5
TextWindow.WriteLine("After loop: N = " + N)
Here’s the output you’d get:
Inside loop: N = 1
Inside loop: N = 7
After loop: N = 13
Changing the loop counter (Line 3) caused the loop to go for two rounds only (instead of 10). Unless you have a compelling reason to tamper with the loop’s counter, please don’t! And don’t tamper with mattress tags!
