These uses are sometimes confusing. I remember to have been asked about 
a sign of a variable I'd never used! It was an internal variable of a 
maxima routine. How could I figure out what sign of it was? To my 
opinion, interactive queries don't make it harder to use integration etc 
inside other 'smart algorithms'. (I don't have tht example at hand now, 
sadly ).

Ther same applies here
