Is this can be done by SORT?

My input is like this:

Yes

It can be done using SUM FIELDS

But what you need to do is

Format the input and overlay the numeric data without comma and decimal

Use SUM fields

While writing to outrec reformat

Please note that both your posts have had Code tags added to them to preserve the spacing of your code/data. Do that yourself next time.

Don't you now have a "leading" sign when previously you had a "trailing" one?

abby.qiong.zhang,
As mentioned earlier, you are now getting leading sign instead of trailing sign which is what NOT you requested earlier.

Alternatively you can use below method so that you don't have to OVERLAY and do the conversion. If your input file is already sorted on key then replace SORT FIELDS= statement with OPTION COPY. If you want trailing positive (+) sign as well, change SIGNS=(,,+,-)

abby.qiong.zhang,

Consult the manual for the difference between SUM and the OUTFIL reporting functions and the influence of EQUALS or NOEQUALS on the process, if this requirement is part of a larger one dealing with records of the same key but different information.
