If you PRINT a record multiple times, "=xx" will be totalled for each
record printed, at the time the printing occurs.

Huh?

Please try the above, along with "=1" on the subtotal/grandtotal lines
(using whatever field would be appropriate for a total, of course) and
report what you see.  Then tell me how the first "follows the standard
semantics of a dummy field" and how the second "does not".
