Let's forget about printing for the moment, since that's a completely separate problem; the only issue is how BASIC09 is treating those quantities. You already know the problem - they're two 16-bit signed integers, and it seems you can't change that.

We already have three workarounds to do it. We're just trying to see if there is a "real" way to accomplish this. It's what we do :)

And -- due to one of the numbers will be negative, the normal maths don't work. That's what started this. One of the three workarounds proposed checks for that by doing something like

if b<0 then b=b+65536

...during the assign to the REAL.

We have several ways to make it work -- but we continue to look for a better way :)
