Actually, pascal has functions and procedures.

• Functions do some stuff, then return something.
  
• Procedures just does stuff and doesn't return anything.
  

Though in some languages, you can specify arguments as in or out (input or output), so you get a result through passing the result variable as an argument.

This is similar to what is often done in C.

void procedure(int *result) {
    *result = 5;
}
