Syntax Problems with map() and apply()

[mark4flies]

I never found the rand() function so I created my own. The built-in function is very nice.

BTW, what is the method for generating the pseudo-random numbers on the HP Prime? Is it still the linear congruential generator? The standard now is the Mersenne Twister.

The HP Prime capability (memory and speed) lend itself to serious applications beyond education and having a superior, modern RNG would be a big step forward.

Thanks again for the help with the original question. I'm learning a lot!
