Simple Array Demo

[Archangel]

Hello,
this little example just cycles through a 26 element array and displays it's value. I wrote it to
teach myself array function, and with help from Jerson it works as expected. I am posting it here to assist noobies trying to grasp array function.

I realise there are likely easier ways to load the ARRAY . . .Baby Steps
Anyone wishing to post more or better examples of ARRAY functions are invited to do so on this post.
