Which, using the above syntax, would appear to be correct.  And I think you 
would get the same result if a puts("foo bar\n"); was done but its been so 
long I won't go anywhere near a bible and say that. :)

I don't think it was the return values, but what it was actually printing, so 
his strings were being interpreted as numbers somehow, or at least that is 
how I read it.

The Kreider libs?  I might have some of that on my coco if I can figure out 
how to get it up here to this linux box.  And if I recognized it when I saw 
it. :)  I built that trig lib by the south american who sent it to Rainbow 
before he died, and I seem to recall I needed to rebuild the Kreider libs 
because of a module ordering problem one of my programs had, but that was 
close to 20 years ago before I started the fade of advanced years.  It may 
also be on rsti, I haven't looked there recently.
