Editing Script Block (section)

== Arrays==
Sometimes a piece of data has several parts, like a position might have an x, y and z. These can be both read and creating within scripts. The main place you’ll see these is inputs coming from scanner blocks which report positions as an array of 3 numbers. For arrays that enter on inputs you can refer to them in 2 ways:
 
=== Reading arrays by X,Y,Z: ===

<pre>distanceAway = N.x      //N.x is the first value in the array, N.y is the second, N.z is the third
S = distanceAway</pre>

This way of referring to arrays only works with arrays entering on inputs, not ones you create yourself.

=== Reading arrays by a number index: ===
<pre>distanceAway = N[0]      //N[0] is the first value in the array, N[1] is the second, N[2] is the third
S = distanceAway</pre>

'''Be aware''' when using numeric indexes the first entry has index 0; the first value is N[0], not N[1].

You can create arrays using square brackets. for example this program would return an array of the numbers 1,2,3

<pre>N = [1,2,3]</pre>

You can of course use variables

<pre>distanceAway = N.x 
N = [distanceAway, 2*distanceAway, 3*distanceAway]</pre>
