Does anybody know if a feature has been added , like "ROW-SUMMARIZE" ? Some way to recalcuate computed fields in row-total situation, the same way we use ON TABLE SUMMARIZE to correctly calculate our computed fields from a column. ?
(Other than , of course, doing all the stuff by arduous coding)

It has been requested as a New Feature, but not yet implemented.

Coding is the only way currently. The way it was shown to me was to first do your request without any formatting and assign a sequence number (SEQ = 2), add BY SEQ NOPRINT and put it to a HOLD file. Then run your request again with a sequence number (SEQ = 1) and add BY SEQ NOPRINT. Include your formatting in this section. At the end use
MORE
FILE HOLD
END
to append the two files together. Aword of warning. if you use a COUNT or CNT. as one of your fields it does not work properly with a HOLD file. Use the following in a DEFINE
-*DEFCNT/I6 WITH fieldname = IF fieldname IS MISSING THEN 0 ELSE 1;
and then replace your fieldname in the request wtih DEFCNT in both sections. When SUMMED it will do the same as count and will work in the HOLD file.
