Interesting that Query/38 had this yet Query/400 doesn't.
However if it were me, rather than move backward, I'd move forward by
converting to a Query Manager query and make use of the UDF Michael
Sansoterra provided in the article I posted a link to earlier.
As an added benefit, a QM query can take advantage of the SQE instead
of the CQE.

I remember doing this in Query on the system/38; I recall that the trick was
to created a calculated field with a formula of +1.
Query/38 also did tables and there were many occasions I cursed WRKQRY on
the 400 for not having this feature.

There is a debit field and a credit field in the record layout.
The requirement is to print a third column which is a running
total. In RPG it would be
runtotal = runtotal + debit - credit
I want to do this with query but can't figure it out.
The Query/400 feature offers only its /summary functions/
accumulators. There are no other accumulators [e.g. running totals]
supported in WRKQRY; i.e. the value of prior row(s) is not tracked,
except for effecting the summaries for the /report breaks/. The
Query/38 feature [DSNQRYAPP] however, does offer running totals;
effectively the same question & response here:
