Hello Ed,

  Thanks for the response.

I'm sure that INT 10h screen-writing calls actually do work on my machine,
as I've used them on other languages.

I seem mistakingly have assumed that the *c*printf (and family) ment
"console" and would, on an X86, use the INT 10h bios-calls, and that the
"normal" printf (and family) would use (redirectable) file-handle
output/input.

Oh, well.  That means I just have to write my own bputs (b for bios) :-)
