Then I've got no idea what's going wrong.  The ``Hello'' message does
appear, right?

You may try uncommenting lines 274 and 275 in texteroids.c.

Not errors, only standard output.

In DPS, context output is buffered.  The executive (the thing you
interact with in dpsexec) works by flushing output before printing
every prompt.  The reason that works is that the executive does not
interact with standard input, but with terminal input which gives it a
chance to print a prompt once in a while.

I have not (yet?) implemented terminal input, but instead have made it
an alias for terminal input.  So you need to type either ``flush'' or
``prompt'' once in a while to get the output flushed.

The error handler runs a new instance of the executive which starts by
calling ``prompt'' which in turn calls ``flush''.
