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.
