All control structures
are divided into the control
statement (which we will explain below) and the
statement block. The statement block is simply a group
of commands that are executed together. This block is
grouped by enclosing the commands within curly braces
({}). For example, the following is a simple statement
block.
{
statement one
statement two
statement three
}
Perl will
execute each statement in a statement block
from beginning to end as a group. When, how, or if the
script will execute the commands however, is determined
by the control statement.
