How do I random letters

Hello,

I know how i can generate random numbres... easy... but, how i can generate random letters from a to Z?

Thanks.

Use Choose

choose(a, b [, c...])

Choose one of the given parameters at random. E.g. choose(1, 3, 9, 20) randomly picks one of the four numbers and returns that. This also works with strings, e.g. choose("Hello", "Hi") returns either Hello or Hi. Any number of parameters can be used as long as there are at least two.

Thanks a lot
