Let's formalize a little: the action of creating a new procedure is known as definition or declaration, and that leads us to introduce new syntactic elements (meaning, things that we can write in our program):

• the reserved word procedure, indicates that we will define a new element;
• a name which represents what our procedure will do, which must always start with capital letters. Something important: the brackets of the end are necessary, we will see why later on;
• a code block, which will be what is executed every time we invoke our procedure. This block starts with an opening brace ({) and ends with closing one (}), similar to what we already did for the program.

Let's see if you got it: write a procedure Drop3Red which drops 3 red stones and a program which uses it.
