Question: How loops with multiple lines?

I may have asked this before, but if so lost answer.

I'm trying to put a relatively elaborate peace of code in a loop, but can't figure out how to have multiple lines. Each command separated by ';' is awkward and seems to cause me to make even more typos then normal and it's hard to read the code.

Is there a way to have command on separate lines with in a loop?
