If no iterator is used, or if an iterator is used the wrong way, OMLoop gets stuck and potentially goes on forever.
We want to generate four random numbers between 1 and 4.
Instead of using forloop to define the number of steps of the iteration, we have used repeat-n : OMLoop will never end and generate four random numbers an infinite number of times...
An abort dialogue window pops up after a while (by default, 500 000 loops). To stop the iteration, choose
a to abort the ongoing calculation.
