I would like to have a possibility to store some information into somewhere, and later use that information as a part of deciding which action to take.

For example.
The object of the task is to display a sequence, which the child has to memorize. The length of the sequence varies. In this example, the sequence is formed by changing the background color of numbered text labels, but the sequence could also be for example a set of sounds or displayed images etc.

We form the sequence by "flipping" the background color of the first label, then setting it back to default and flipping the second label and so on. Now, what we'd like to add in this case, would be a pause between each of the color-change (e.g. a short moment when all of the labels are un-changed).

There is a possibility to achieve this "pause" -action by adding an additional timer between each color-change, but in the case of a relatively long sequence, it would mean for example 9 additional timers and that much more complexity to the task.

As I see it, one possibility would be to store the name (or ID) of the next timer to some kind of variable, and then run a "general" pause timer which would later on use that stored information to start the next timer (which would begin another color-change). An image of this idea is attached, maybe it describes the idea more clearly...

Another possibility would be also to group the timers somehow and iterate through all of them, keeping a pre-defined pause in between each iteration (maybe in this case the so called pause wouldn't even have to be a timer, but it could also be freely defined, like showing a piece of text or an image or what ever...)

One thing to note also is, as I mentioned earlier, that even though in this case I'm talking about mostly timers, this logic should be applicable also to other objects, such as sounds/images etc.
