# Alphabet

The J alphabet is the ASCII alphabet and consists of:

> 26 lowercase letters (a to z)

> 26 uppercase letters (A to Z)

> `0 1 2 3 4 5 6 7 8 9
> = < > _
> + * - %
> ^ $ ~ |
> . : , ;
> # ! / \
> [ ] { }
> " ` @ & ?
> ( )
> '`

There are a few characters that sometimes cause confusion. The - (minus) character is different from the _ (underbar) character and there are three different quote characters:

> ' | quote
> " | double-quote
> ` | back-quote

If you try an example and type " (a double-quote) instead of '' (two quotes) you will be disappointed that your result is not the same as in the book.

The . (period) is usually called dot.
