	OK, I have found but I think I don't have time enough to quickly fix it.

	When you write 100 1024* 50 *, you create a logical name ('1024*'). As 
you have created a name, evaluation() creates for you an algebraic 
expression :

	'(1024*)*50'

that cannot be evaluated because parenthesis avoid first '*' to take 
argument in stack. A quick and dirty patch is to avoid in name all 
charaters that is not in (A-Za-z0-9) set, but I'm not sure that there is 
no side effect.
