If statement in Thinkscript

Dear Fellow ThinkScript Coders of Stack Overflow:

I am a beginning thinkscript programmer and I am learning the syntax of thinkscript pretty fast. However, I am having trouble with the if statements. I understand you can have one statement inside of an if block but is it possible to have multiple statements in an if block?

Not: if (condition) then (this) else (that);

but: if (condition) then { (this); (that);};

Thank you in advanced.
