How can I evaluate code stored in string?

[dmytro starosud]

Hello,

Is there in Smalltalk (GNU Smalltalk is used) something like "eval"
function.
I want to do some kind of following:

str := '2 + 3'.
out := str evaluate. "and out equal 5"

str may contain any valid Smalltalk expressions.

thank you

You can use the Behavior class:

Behavior evaluate: '2 + 3'
