Hmm?  Peanuts?  Rick Astley?  (And also, The Game?)

Are these sort of like memes?

Will there be a test?

Okay, so to summarize...
If I do 5->A, the calculator will create a (temporary?) variable, and store 5 to it?
And if I do 5->{A}, the calculator will go to location A in the RAM and overwrite whatever was there then store 5 to it?
And I should avoid using curly braces except for L₁ and L₂.
Stick to strings and appvars, because the other data types are weird.
Am I right?

Also, I have several more questions:
3) How much is a byte?  I think nemo said that 1 byte can hold up to 255, so would that mean that 1 byte is equal to 2 hexadecimal characters? (like FF would be 1 byte?)
4) DJ Ommimaga said that there are about 712 bytes of space in L₁ (and probably L₂) - so I would use those two if I wanted to construct a list of some kind?
5) What are the differences between the variables A-Theta and using Str, Pic, and GDB?  Is it safe to use curly braces around those?
6) I think curly braces are used primarily for creating lists in safe RAM spaces - my numbers would be in sequential order.  Is that correct?  What other things can pointers be used for?
