Dear Adrian,

Yes, you are right: the multiline feature no longer works.
This is a consequence of the latest "improvement" of the plug-in system,
which now allows for the execution of several inputs in succession.
If I have some time, then I will try to fix this issue, but this is
not completely trivial.

Best wishes, --Joris

PS: I did fix the compilation issue concerning iostream.h;
also for the other example plug-ins.
