There remain problems in calling functions from the msg box. It is 
true that you can avoid problems with a *simple* function call by 
avoiding  "put", but there are problems with compound statements.

For example: In the stack script defined the function

function sq x
return x*x
end  sq

If you enter into the msg box sq(3) you get 9 as expected. But if you 
enter 3*sq(3) you get an error.

This is a serious problem using MC/Rev in education. I would like 
students to be able to use the msg box for such simple tasks.
