A.5 Statements and Blocks
Programs are composed of
statements
often grouped together into blocks.A statement ends with a semicolon
(;), which is optional for the last statement in a
block.A block is one or more statements usually surrounded by curly braces:{
$thousand = 1000;
print $thousand;
}
Blocks may stand by themselves but are often associated with such
constructs as loops or if statements. |
