Ya' know, put together with the VT APIs, Qp0zStartTerminal() might have 
some intriguing qualities. When STDOUT is sent to the terminal, an 
[Enter] key is required to end the session. OVRPRTF STDOUT to a DBF has 
no such restriction.

I haven't used pipe() but looked at it before posting. I didn't see an 
obvious way to "tell it (the sacrosanct C program) to use those 
descriptors", hence, the post.

For now, I guess it just has to wait. File output 'works'.
