Depends on what "one go" means. My own batch module has a Batch.Collect
command which will trigger garbage collection, remember the current
position in the script and enable a background task (and stop the script

The background task will detect that the GC (also a background task) has
happened and resume the batch job where it left off. So for the user it
looks like it is "one go", although in practice the Oberon main loop is
running during the process.
