(quote my-var) <font color="#008844">; returns MY-VAR</font>
my-var <font color="#008844">; still error: unbound variable</font>
(set (quote my-var) 111) <font color="#008844">; give MY-VAR a value, make it exist</font>
my-var <font color="#008844">; returns 111</font>
(quote my-var) <font color="#008844">; returns MY-VAR</font>
<font color="#008844">;; Same as above but using the ' read macro for quote</font>
new-var <font color="#008844">; error: unbound variable</font>
'new-var <font color="#008844">; returns NEW-VAR</font>
new-var <font color="#008844">; still error: unbound variable</font>
(setq new-var 222) <font color="#008844">; give NEW-VAR a value, make it exist</font>
new-var <font color="#008844">; returns 222</font>
'new-var <font color="#008844">; returns NEW-VAR</font>
