Passing/Evaluating Strings as Executable Code

[Jake]

Oh, I see why that's not working now, the logic was overwriting 
the Attribute.
 
Still, it would be good to know if you pass a string as an expression.  
I've search the documentation and some VB stuff online, but I haven't seen 
an eval() like function. Has anyone else used/seen something like that in 
E-Basic?
 
Thanks,
Jake
