values into mul

Post by joejoe »

Hi,

I am trying this:

Code: Select all

(set 'abc "8888")
(println abc)
(println (mul 2 abc))
and getting this:

Code: Select all

8888

ERR: value expected in function mul : abc
What would be the way to get values into the mul function?

Thanks!

Use read-expr.

Code: Select all

(println (mul 2 (read-expr abc)))
(λx. x x) (λx. x x)

rickyboy,

You're the man, thanks big!

I hadn't gotten so far as the read-expr, much appreciated! =)
