You could start a recursive edit, during which you could mark the text
you care about. Then exit the recursive edit and the function can copy
the region and insert it into the other buffer.

What Stefan was saying is that you should do something like:
(let ((first-buffer (current-buffer)))
(set-buffer "dict.txt")
....
(set-buffer first-buffer))
switch-to-buffer and other-buffer are intended for interactive use, not
use from programs.
