We do not currently support the list comprehension sort of construct that you describe. However, you can use the timer control to simulate iteration. Hopefully the following example will help you get started.
Add a timer control to your canvas. Change its properties as follows:
TimerEnd: UpdateContext({TStart:100});UpdateContext({TStart:0});UpdateContext({counter:counter+1})
End: 2
Start: TStart
Text: "Timer: " & counter
Now hit F5 to go to preview mode. Click the timer control. You will see it steadily increasing--you can speed up by setting Interval to 0.1 or something like that.
What is happening is that the timer is going from 0 to 2. When it hits 2, the TimerEnd rule resets TStart to 100 and then to 0--the variable's value needs to change for data to flow. This will cause the timer to continue in a loop. We also increment
counter--this value is displayed on the timer itself because of the Text rule above. What you now have is essentially a while loop and you can add Collect statements to the end of the TimerEnd rule to collect values of the counter.
You can also set termination condition:
TimerEnd: If(counter < 5, UpdateContext({TStart:100});UpdateContext({TStart:0});UpdateContext({counter:counter+1}), false)
I hope that gets you started :-)
