Creating a basic Mindscript program, while not as simple as the NQC equivalent, is still quite simple. Below is an example of a simple program that will run one motor indefinitely:

program myFirst
{

   output left on 1

   main
   {

      on [left]
   }

}

Let's take this one step at a time. The first word is program, quite simply it tells the brick that it is approaching a programs start.

The next element is myFirst. This is the programs name. It makes little difference what we call the program. But it is essential that we give it a name.

The next element is { (opening curly bracket). This indicates the start of the program. The end of the program is defined by a } (closing curly brace). You'll notice another set of curly brackets after the word main. In that context it's obviously not starting and stopping the program. Instead it denotes the satrt and finish of the main block of commands (we'll come to main in a minute). What is important is that these curly braces can be used in differents contexts, but these must always appear in pairs. A common error is to start a block of commands and then to forget to close them. A good habit is to place the start and finsh braces at the same time; so they aren't forgotten.

The next line starts with the word output. An output is something the robot can control. In this case it's a motor; motor 1 to be precise. We're declaring that we intend to use motor 1 and that we'll be calling it left. From now until the end of the program the robot will know that we are talking about motor 1 whenever we use the word left.

If we planned on using the second motor, or the light sensor, or the touch sensor, then we would also need to declare them in this area in a similar manner.

The next element is the word main. This is where the brick will start looking for commands to execute. In this example there is only one command and that is to turn the motor (we declared as left) on.

If you download and run this program your robot will go for a spin. So that's it! You've created your first Mindscript program.
