Imagine that you have a file, in which you mention a Miss Jensen several times, when someone comes in and tells you that she just got married to Mr Jones. You want, of course, to replace each and every occurrence of Miss Jensen with Ms Jones.
Imagineu que teniu un fitxer, en el que mencioneu a Miss Jensen vàries vegades, quan resulta que algú ve i us diu que s' acaba de casar amb Mr Jones. Per descomptat, voldreu substituir cada ocurrència de Miss Jensen per Ms Jones.
