compound statements
• a block is a sequence of statements delimited by curly brackets (braces)
that defines a scope
• compound statements that control flow:
• if (EXPR) BLOCK
• if (EXPR) BLOCK else BLOCK
• if (EXPR) BLOCK elsif (EXPR) BLOCK ... else BLOCK
• LABEL while (EXPR) BLOCK
• LABEL while (EXPR) BLOCK continue BLOCK
• LABEL for (EXPR; EXPR; EXPR) BLOCK
• LABEL foreach VAR (LIST) BLOCK
• loop control via next, last, and redo
• if ($model == 3000) { $os = 'mpe' };
