Yes, this works fine.

Running file1.oz (ranamed to File1.oz) at first resulted in the
following error message:

Adding an `end' to the end of the file then resulted in the following
error message:

Since I was unable to obtain a port number from the output from
running File1.oz, I was unable to run File2.oz (renamed from
"file2.oz").
I have already experienced TCP/IP port-related errors in Windows XP
Professional, Service Pack 2, related to auto-updating another
application, DrScheme, because of this problem; unfortunately, when I
tried to add TCP/IP port permissions to that application through the
Control Panel -> Windows Security Center -> Windows Firewall ->
Exceptions -> Add Port... feature, this function did not seem to work.
I suspect that if Mozart/Oz uses a TCP/IP channel for inter-process
communication, then this could be the cause of the error.
Which TCP/IP port number should be added?
