RE: [Axiom-developer] spool bug?

[Weiss, Juergen]

I think there are better ways to achieve the same results (spool
commands 
on unix, X-Term session capture etc.) than to change Axiom. With the
)sys command you can call an editor or a shell which will not work
within a pipe -- at least not as expected.

With best regards
