There could be a block (in the control section) that would mark a certain point in the series of actions. Also, there could be a go to block that would go back (or forward) to a certain point in the script. For example:

mark step
ask and wait
if <answer=67> then
|say for (2) seconds
—-else———————————————-
|say for (2) seconds
|go to step
——————————————————-
say for (3) seconds

If the question is wrong, it will go back to the step, “ask”.

You can just use really easy workarounds.

So basically a goto, one of the most despised commands in programming?

Perhaps, I dunno, might be useful.
