Find and copy files modified today

Hello,

I am trying to find and copy files modified today from one directory
to another. Something like:

cp find /dir1/P*.DAT -type f -mtime -1 /dir2/

Is there a way to combine the cp and find commands on a single line?
I don't think that there is, so instead I made a script to do this:

#!/bin/ksh
PATH1=find /dir1/P*.DAT -type f -mtime -1
PATH2=/dir2/
cp $PATH1 $PATH2

The individual lines do work, but when I try to run this as a script,
I get "/dir1/PTEST.DAT: This: not found." when it tries to do the
copy. I know I'm missing something obvious, but at this point google
has failed me...
