Joe – The WriteString(), WriteLn(), etc., functions only work with DOS
windows. You found that out when you used OpenInputOutput(). There are some
libraries available that allow you to perform simple I/O with Intuition
windows. Rob Peck's book "Programmer's Guide
to the Amiga" has examples (in C). If you're interested I posted some
translations of the programs in that book in DL12 here. There is some info in
that file on how to obtain the complete set of translations. If you want, I
can post just the file(s) that pertain to the console device.
