That's the problem. It's more important to understand simple code thoroughly first rather than trying to dive into looking at someone else's more complex program. Or if you're mainly trying to copy it to your calculator using SourceCoder, then at least make sure you have things like no extra commas where they're not supposed to be. As far as learning, start small: A "Hello World" program, a quadratic equation solver, or a number guessing game, for instance.

That sounds good, then. But random numbers and lists are both new concepts to you, correct? Something like randInt(X,Y) should be straightforward, generating a random number between X and Y, but lists are more complex. They are prefixed with that small L if they have a custom name, or they can be one of the six lists typeable from the 1-6 keys on the keypad, L1 through L6. Lists have between 1 and 999 items, accessed by, for example, L1(1) for the first item, L1(3) for the third, L1(10) for the tenth, etc. You set the size of lists using the dim command: 42->dim(L1) sets L1 to have 42 slots for numbers, L1(1) through L1(42).

Notice the "SYN" by error 514: that is short for Syntax and means you have a syntax error. Whereever the cursor goes to when you choose 2: Goto is where the error is, so look for typos.
