   You can leave a loop or function early with exit, and you can terminate   
   the program with halt. Both should be used sparingly, as they are in   
   effect hidden gotos. They are usually used to leave after error   
   conditions, when the use of if/then/else structures would result in   
   cluttered code.

   You don't, that is BASIC-style programming. In Pascal you call a   
   procedure or function, in hardware-near cases via the exitproc-chain. In   
   addition, there are fuction variables which you may whish to look into.
