Clear all repetitions at once

[hartmut]

I have a repeating field which has 40 repetitions and I would like to make a script which clears the contents of all the repetitions at once. Is there a calc to do this? Like (1-40)

Reserve the repeaters for utility purposes only not storage, I practice the rule only to use them as repeating calc'fields ... however to your question:

The entire approach uses the feature I have oval'ed...
