Hi,

I have amended Guido T's code a little as you say that you want your
new variable to be numeric.  Both yours and Guido T's code have the new
variable as a character one.  See change in the length statement and
use of the INPUT function below:

data x;
length var1 $100;
input var1 & $;
y = input (resolve('%eval('||var1||')'),8.);
cards;
1+ 2 + 3
(3 + 4 ) * 5
(30 - 20) + 100
;
run;

Regards,

Tony
