[Oberon] Essential facility missing.

[Douglas G. Danforth]

In the BlackBox version of Oberon (Component Pascal)
one has access to the underlying operating systems directory
structure.  So when one selects Files->Open one sees the
directories.  One can then specify that they be listed in
chronological order (or reverse order).  The same holds
true when one descends into a directory and sees the files.
Here's what that looks like

You obviously are using the a version of Oberon not suited to your needs.
