Final message
Problem
An END phaser runs after the main code, so it sees the
final state of your variables — which makes it ideal for a
summary.
Declare a counter $count set to 0, and
write an END phaser (place it before the main code) that
prints processed $count items. Then, in the main body,
increment the counter three times with a loop. The summary should report
the final count, not the value at the moment the phaser was written.
Example
The program prints:
processed 3 items
