Hello Monks,

I have tried to find an answer on this issue for the past day or so. I saw a similar thread: Value of a scalar specified by a second scalar ,but still came out empty handed. My problem child is here:

chomp($exp = <STDIN>);
 $out = 'exp';
 print $$out, "\n";

[download]

I'm not sure if referencing is the proper thing to do here since I am getting an "unitialized variable" here. The <STDIN> is an expression along the lines of:

(7 * 3) + (2 + 1)

I am trying to get this block to return the answer, which in this case is "24". When I just do:

print "$exp\n"

I get the expression back and not the answer. I was hoping I could get a few pointers on this.


thank you in advance.
