Hexagrid

Hexagrid was designed by Emil Svensson (User:fr34k) in 2008. The name comes from how one codes in Hexagrid (hexadecimal grid).

Overview
Initially, when you code in Hexagrid, one has a virtual grid of the hexadecimal codes with pointers starting in the uppermost left corner.

v >0 1 2 3 4 5 6 7 8 9 A B  C D E F

''This is only for clarification, and is never shown when coding. One has to keep track of the pointer in his/her head.''

By moving the pointer around one can add hexadecimal codes to different stacks.

Basics
Moving the pointer, defining a stack and adding data to it

Before we can code anything we need to define a stack that we want to work with. Remember that you can work with as many stacks as you like, the only rule is to work with the coding inside the stack limitations ({ and }). Let's call our stack myStack. myStack{}; First of all we clear the stack and reset the pointer myStack{!}; After that we can move the pointer using <, >, ^ and v. Let's say we want to move our pointer to A in the grid.

We move the pointer two steps to the right, then two steps down. myStack{!>>vv}; Let us then add this data to the stack using the + command myStack{!>>vv+} If you want to move the pointer anywhere else, keep in mind that the pointer now points at A.

Now let's output the stack. We then use the o command myStack{!>>vv+o};

Wich would output A

Hello, world!
This is a Hello, World! program in Hexagrid stack{!v+v+^>>+<+>+<>+<>+vv>+<^^^+<<+>v+>>+<+>vv+^^+^<+v+<>+<<+^>>+<+o}; which will output Hello World! or in hexadecimal code 48656C6C6F20576F726C6421
