Example Edit

If I have no pants and I must scream then: I would scream without pants. That's what I would do.

This loops the next part of code if the variable Applejack is equal to 99 and the variable Spike is equal to 12.

This is equivalent to the following Java code: 

if (iHaveNoPants && iMustScream) { screamWithoutPants(); }
