# // | Example, you want to have a spacing in the way your stuff is written to the screen.                    |
# // | You can have characters already fully assembled, and then select the distance with the array selector. |
# // | You can use this idea in a couple different ways...                                                    |

# // | Using arrays within strings adds on a lot of extra stuff that could be saved |
# // | by pulling from the array first...                                           |

# // | Sure, you're declaring more items... but you could do it THIS WAY, |
# // | rather than to have to add in a lot of "$( $Array[10] )"...        |
# // | Because, that gets tedious as well.                                |

# // | Now, if we cast the variable $Dash to [Symbol]::New(),                      |
