DESCRIPTION

16       A scheduled code block is one that is intended to be run at a specific
17       time during the loading process.
18
19       There are five types of scheduled block:
20
21         BEGIN {
22               # Executes as soon as this block is fully defined
23               ...
24         }
25
26         CHECK {
27               # Executes after overall compile-phase in reverse order
28               ...
29         }
30
31         UNITCHECK {
32               # Executes after compile-phase of individual module in reverse order
33               ...
34         }
35
36         INIT {
37               # Executes just before run-time
38               ...
39         }
40
41         END {
42               # Executes as late as possible in reverse order
43               ...
44         }
45
46       Technically these scheduled blocks are actually subroutines, and in
47       fact may have 'sub' in front of them.
