Re: Howto use fields "by name"

[afvaiv <afvaiv@xxxxxxxxxx>]

Well, thanks again to all for the new answers.

Martin, thanks for the link to your code to CRTCSVDTA. I'm studying it
and will try the reverse way.

Douglas, you are right, reading all other suggestions I missed Charles
quote when I wrote that nobody had answered my original question.
Anyway, I had searched through the archives first, before posting the
original question and hadn't found any thing... (although he said: "This
has been discussed numerous times in the archives") Well I could not
find it.

Rich, thanks for your comments. I had thought of doing it that way, and
it's precisely for avoiding it that I asked if it could be done some
other way...

I think I have it quite more clear now. Thanks to all again.
