Ready to tackle programs that can reach above the bar? As they say in Red Stick, There is beaucoup storage there waiting for you. In this video, you will learn how to call a subroutine that switches to 64-bit addressing to create 10 megabytes of storage above the bar. Think of what you can do with that amount of storage – Read an entire file into memory – build a data structure for all of your records. Besides the video, there is a working main program and a subroutine you can use to get started. 

These are easy to pick up – handy, too, if you want to write 64-bit addressing programs. If you are changing addressing modes from 31 to 64, say, you have some 31-bit addresses that need to be expanded to 64-bit. Well, these are the instructions you need. Read about them here and here.
