Rats! I tried something along those lines and gave up. I think I
must have had a typo in what in was trying, which was, in essence,
this:

sed -n '/(.*)/{h;d};{G;s/\n/ /p}'

(not sure why I was using -n and not simply dropping the 'p' but
that's the nature of "fiddling" I suppose).

Anyway, thanks. It was irritating me...

Thanks so much.
SED is not an absolute requirement.
But so far the rest of the project is in SED.
I do want to learn PERL. I've fiffled a bit.


*+-sed -e '
*+- /^([^)]*)/{
*+- h; # remember the (qqq) part
*+- d
*+- }

*+- / [1-9][0-9]*$/{
*+- G; # strap the (qqq) part to the list
*+- s/\n/ /
*+- }
*+-' yourfile

I think you just demonstrated Ed's point.

(And that's not standard sed syntax; it will not work with many
versions of sed.)

Note that anything sed can do can also be done by a
machine consisting of a read/write head, a tape of symbols,
and a few rules.

Nobody who confuses computability with expressivity can be
regarded as a bona fide expert in computing.

Well, ... I find the "specification" to be rather ambiguous, but
within
the realm of reasonable interpretations of specified behavior ...
/^(qqq)$/h;/[0-9]$/{;G;s/\n/ /;p;}
e.g.:
$ echo '(qqq)
> aaa 111
> bbb 222' |
sed -ne '/^(qqq)$/h;/[0-9]$/{;G;s/\n/ /;p;}'
aaa 111 (qqq)
bbb 222 (qqq)
$
