After Header Computations
An After Header
computation can reference page item values set in prior execution
points. The only prior execution points happen to be the before
header computations and before header processes. After header
computations can be used to set page item values in the after header
region and below. In Figure 12.8, the after header page item was set
using an after header computation. It could not have been set with
any execution point later than the after header computation or after
header process.
After Header Processes
As shown in Figure 12.8, the After Header process
is actually executed prior to the after header region. For that
reason the after header process can still be used to set page item
values in the after header region. It can also reference any page
item values set by an earlier execution point.
