Announcements of available shared folders

Bills is a folder that provides a convenient environment to enter amounts and have them collected and summed up.
Use is very simple: you slip into the folder, enter your amounts and tap done when done.

Bills automatically saves the current stack for you as you enter the folder and switches to right-aligned, 2-digits after the point fixed number display. You're encouraged to flick through the stack when you entered all amounts to ensure they're correct. As you exit the folder, your previous stack is restored.

Here's a sample session:

As you enter the folder the stack is cleared.
To begin
Bills1.png (6.27 KiB) Viewed 4812 times

Enter some amounts, then switch to full-screen to check them.
After entry of amounts
Bills2.png (15.29 KiB) Viewed 4812 times

Tap done.
Bills3.png (14.32 KiB) Viewed 4812 times

Note, a variable, "last", is created which stores the two result lines.
If you want to keep a permanent record of this, rename "last" to something like "Skiing Bills Dec 2010", or email your stack with a tap on "email".

Exit Bills and see your previous stack.

That's it. A simple, but hopefully useful tool.

Note to Programmers

If you're interested in learning how to program ND1, this folder is an interesting one to study.
It makes use of hidden functions, and uses both JavaScript and RPL to accomplish tasks.
It also uses .onenter and .onexit to execute automatic folder actions.
