BlockClosure

Hi all. I need to know how can I convert a string or a Stream content into a
BlockClosure instance.
My point is  i want to write a formula wich has literals. then i want to
replace the literals for specific magnitudes and in the formula and
evaluate the result.

how anyone help me?
TIA
Pablo

Not sure how complex is your formula, but have you looked at parsers like  
SmaCC?

I'm confused as to why you can't us a BlockClosure in the normal way - where
the literals are block variables and you pass the actual values as arguments
to the block when it is evaluated.

myBlockClosureFromString := Compiler evaluate: '[:each | each class

Be carefull about the evaluation context (Compiler evaluete:in:).
