Looping and Sequence tasks

Let's take a look at the containers,…and we have three containers.…First we're going to look at the ForLoop,…and the ForLoop container like its peer, ForEach,…is very similar to the same constructs…that you find in programming languages.…The first thing we did, we created a counter…that we can track, and we set that up under variables.…I named it MyCounter, and it's a Int32,…and its value is one.…And then within the ForLoop, we came through…and we initialized it, this is an InitExpression,…@MyCounter = 1, and then we evaluate,…so we evaluate that MyCounter <= 3,…and based on the evaluation, we're gonna continue the loop.…

Now every pass we're gonna add one into the counter,…which takes the current value of MyCounter…and increments it by one, and we'll say, "OK."…And all's we're gonna do is call our little Script task,…the Script task simply has a message box in it…that's going to pop up and say, "One, two and three,"…so that we can see that the loop actually executes.…We'll come over here and execute the package.…
