OK, thanks. That gives me some perspective. I need to read Streams
in Oberon and in A2 again and review use in Mail again.
In the Oberon subsystem of UnixAos, I encountered a limit on the
number of executions of Files.Old(). According to memory, enough
executions froze the system. Appeared that the limitation came from
Linux. Each execution created a temporary file until a limit was
struck?
That motivates my interest in the use of Files in Streams.
Understanding software (or any technology) retrospectively can be a
challenge.
Thx, ... P.
