ON EVERY ROW
Defines printing commands for each row in a report.
The ON EVERY ROW control block specifies the action
to be taken by the runtime system for every input record that is passed
to the report definition.
ON EVERY ROW control block
for each new input record that is passed to the report. The following example is from a report
that lists all the customers, their addresses, and their telephone numbers across the
page: ON EVERY ROW
PRINT r.fname, " ", r.lname, " ",
r.address1, " ", r.cust_phoneThe runtime system delays processing the PAGE HEADER control
block (or the FIRST PAGE HEADER control block, if
it exists) until it encounters the first PRINT, SKIP,
or NEED statement in the ON EVERY ROW control
block.
If a BEFORE GROUP OF control block is triggered
by a change in the value of a variable, the runtime system executes
all appropriate BEFORE GROUP OF control blocks (in
the order of their priority) before it executes the ON EVERY
ROW control block. Similarly, if execution of an AFTER
GROUP OF control block is triggered by a change in the value
of a variable, the runtime system executes all appropriate AFTER
GROUP OF control blocks (in the reverse order of their priority)
before it executes the ON EVERY ROW control block.
