What kinds of circumstances would lead you to writing a function versus using a loop?

The idea is that the main program should be more like pseudocode where someone who wasn't a programmer could probably understand it because it didn't contain any of the details.
Simplified example:

Program:
... GetUserInput ()
... ProcessUserInput ()
... DisplayResults ()
EndProgram.

The circumstances where a function would be useful instead of a loop is:

When the programmer wants to call a method from memory

In computer programming, when a programmer uses a function, he does this to put a piece of code which can be called to action at any time. On the other hand, a loop is used when there is need for repetition of some lines of code.

As a result of this, a function is used when there is a need to call a method which are lines of code into action so that they would execute commands.
