I stopped trying to use HOpenRF (though it did open the file correctly), 
and am now using FB's OPEN statement. This is only because I couldn't 
find out how to read/write with HOpenRF. Anyway, FB's OPEN statement 
worked fine with "READ# 1, theString$", but not with "READ FILE....". 
That completely froze the system.

Also, now that I have a way to open raw resources, I resumed work on my 
communications program. For file transfers, the client needs to open 
another connection to (current port + 1). So if the client is connected 
to x.x.x.x:5500, file transfers are done on x.x.x.x:5501. I am using the 
"TCP Demo" source code for my program. I don't know how to open more than 
one simultaneous connection using that code.

Anbody know how to do this?
