 The Applesoft general routine to print characters on screen is in `$DB5C` and is named `OUTDO`.
 
 Here's the routine, taken from [S-C documentor website](http://www.txbobsc.com/scsc/scdocumentor/).

 The routine is called with the accumulator containing the character to print every time Applesoft needs to print something (like when using `PRINT` or `INPUT` or ... `SPC` !)
 
 The routine that will effectively print the character on screen is `COUT` (in `$FDED`here named `MON.COUT`) but the `OUTDO` routine here is the pre-treatment of the character to print.

 This little program will demonstrate what we learned here.
 
 It will fill the screen with one kind of character, using four `SPC` statements with a parameter of 240.
