1) As stated above - start a new topic.

2) Please use the SEARCH facility as this has been covered many times in the past for differing reasons.

3) Learn to use the code tags

You go to the manual. You look in the index. You follow the references. You look to see that what you find does what you want. You code it and test it.

You will find it also possible with WHEN=GROUP, but since you only want plain sequence numbers within a key, it will be more efficient the other way.

That's roughly what I was getting at.

I am going to start a "Fields Box". This is like a "Swear Box". Every time someone uses INREC FIELDS, OUTREC FIELDS or OUTFIL OUTREC, they have to contribute a small amount of currency to the "Fields Box".

Also, clearer (to me) to use OVERLAY to append data to a record:
