Thanks for picking that up, it is very useful for automating the
creation of Oberon images.

Any particular reason why you did not keep the other changes in my pull
request, which added Return values to commands that are likely to be
batch-automated?

or in case you rebased your repo again:

I know changing the compiler is tricky, as it makes bootstrapping harder
(you cannot compile the compiler on a system that does not have the
Oberon.Return PROCEDURE yet). But the other commands (ORL.Link,
ORL.Load, System.Free, System.CopyFiles, System.RenameFiles,
System.DeleteFiles) should be straightforward.
