RCL-57

[Didier Lachieze]

This is a nice emulator, it works fine on my iPad mini. I like the way the prefix keys (2nd , INV) are highlighted when pressed. As there is no haptic feedback it helps confirming the key press. And the alphanumeric display of program instructions is a nice improvement over the original TI-57, I like the way it's done, keeping the LED display style.

I have one question: what is the meaning of the arrow close to 'Deg' on the x key? It's not on the TI-57 keyboard layout.

Well, I've been struck by this one while modifying a program : on the TI-57 a new instruction is inserted at the step displayed on the screen, while on your rebooted version it's inserted at the step after, which puzzled me until I realized it was intentional.
I understand why you've changed it, but as I'm using also a real 57 as well as go57c on Android I would like to have the option to keep the original TI-57 program editing for consistency.
