Very Computer

Hi all,
I have written function for using in Emacs.  This function will keep the
required sentense in "kill-ring" variable.  So I can patse it anywhere
by yank it.  But after I use Xemacs, it seem that Xemacs patse text by
using sentense from other place.  How can I rewrite my function to be
able to use in Xemacs ?
Please help me and Thank you in advance.
Best regard,
Kanokkiat Kanokphara.
