Belongs to Function Group: Creation of Output Reports
The statement AT TOP OF PAGE is used to specify processing
which is to be performed when a new page is started.
See also the following sections in the Programming Guide:
A new page is started when the internal line counter exceeds the page
size set with the session parameter PS (page size for
Natural reports), or when a NEWPAGE statement is executed.
Either of these events cause a top-of-page condition to be true. An
EJECT statement causes a new
page to be started but does not cause a top-of-page condition.
An AT TOP OF PAGE statement block is only executed when
the object which contains the statement is active at the time when the
top-of-page condition occurs.
Any output created as a result of AT TOP OF PAGE
processing will appear following the title line with an intervening blank
line.
This statement is non-procedural, that is, its execution depends on an event, not on where in a program it is located.
An AT TOP OF PAGE statement must not be placed within an
inline subroutine.
