I have a clarification to ask about your answer for setting several fields. You
said several fields can be set thusly:
$ recset -f foo,bar -s XXX foo.rec
However, that seems to only work if you're setting multiple fields to the same
value. This doesn't seem to work:
$ recset -f foo,bar -s XXX,YYY foo.rec
That results in both foo and bar being set to "XXX,YYY". Am I doing this wrong?
