Julian/Lloyd,
I was not doing the Pick in a loop. I was just picking and had hoped
(naively) that the Export module will store the values until it or I was
done picking.
I will try to implement your suggestions - although I wasn't having much
luck this morning. I will keep on trying.
Thanks for your help.
Gerry

Although I believe that I resolved the difficulties I was having,
it may be worth mentioning what plagued me for a while. Even when I
used ForEach, the difficulty was knowing where to put something
"outside the loop". Everything in the visual program is potentially
iterated. The answer advised by the user guide was to put the
loop (including the ForEach) in a separate macro, which I tried with
success. I guess I could have used ForEach's Last parameter as an
alternative.
Whether all this is any help to Gerry I don't know.

If you are doing this in a ForEach type of loop, then you should accumulate
the results in a group or list. Then, do the Export outside the loop
(i.e., when it's done). The file will then have all of the accumulated
points. If you are doing it in a Sequencer-based loop, then yes you would
be overwriting. In that case, pass the output of Sequencer to Format to
create a unique file name for each iteration and pass the filename to
Export.

Gerry,
I would guess that you're using some form of DX loop to write your
multiple points. I have been trying to work with DX loops the last
few days for a different purpose and now believe I understand the
difficulties better. What may be happening with you is that a new
file is being written for every point, overwriting the previous one,
so that what you end up with is - of course - a file containing only
the last point.
It's all there in the User Guide (section on iteration), but it takes
some working out.
I can give you further pointers if you need them.
Regards,
Julian Gallop
