Is this supposed to work? It doesn't.

    $ cat foo.sh 
    PREFIX=foo
    SUFFIX=bar
    . << xxxEOFxxx
    ${PREFIX}${SUFFIX}=abc
    xxxEOFxxx
    echo foobar=${foobar}
    $ sh foo.sh 
    foobar=
    $

This is FreeBSD 4.5-REL. If you write the '${PREFIX}${SUFFIX}=abc'
to a file and then input that file using '.' then it does work.
So why the difference?

Thanks,
-Archie
