Storing Data on Disk
Storing something on disk, permanently, is just as easy as using regular variables. Just place the ^ (caret) character in front of the variable name. The example saves a string in the variable ^x which is different than the regular variable x. We'll discuss this topic in detail soon.
This example will display the current value of ^x before updating it, each time you run it.
x = 4 println "x = ", x println "old value of ^x = ", ^x ^x = "random number: " & int((rnd()*10)) println "new value of ^x = ", ^x
