Pointer

The most important concept in Infant Lang is the pointer 👆

The pointer is a number that points to the position of the arrow in the number line 📊

The pointer is initialized to point the box 0. It can point only to whole numbers.

It can move left or right but cannot go beyond the limits of the whole number line

tldr;​

  • The Pointer is initialized to point the 0 box 📦
  • The Pointer can hold only whole numbers 📊
  • The pointer can be moved with the move 🚗 keyword.
  • The pointer can be moved left or right with the left 👈 and right 👉 keywords.

The move keyword​

The pointer can be moved left or right with the left and right keywords. Let's see how it works:

Have a look at the following snippet:

move pointer right

What does this code do?​

The move pointer right moves the pointer right 1 box 📦. Which in reality will increase the pointer by 1 👈. We can also move the pointer right with the left keyword.

Moving Pointer value to a negative number will cause the pointer to go beyond the limits of the whole number line 📊. It will throw an error and stops the execution of the script.

Move pointer for more than one box​

The pointer can be moved for more than one box with the movement number associated with the move keyword. The movement number defaults to 1. Let's see how it works:

# This line will move the pointer to the right by one box
move pointer right

# This line will move the pointer to the right by 12 boxes
move pointer right 12

We can also move pointer conditionally with the if keyword or move insanely fast with the for keyword which will be explained in the upcoming sections.
