(let ((char (read-char dialog-stream)))

[Santiago Carbonell]

In this construct:

 

(let ((char (read-char dialog-stream)))

...

 

char is a function or a variable?

 

Thanks

char is a variable scoped to the let.

(let (list of variable assignments)
  do stuff
)

(let ((char (read-char dialog-stream))
        (i  1)
        (wallaby "fuzzy"))
   ; something about a single fuzzy wallaby with character)
