They're not talking about "masking away" characters from a given character set in a single string. They're talking about masking multiple strings together in order find out which characters those strings have in common. Hence: southern - yourself ---------- -ou--e-- (where `-` (minus) is the masking operation.) I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.	[reply] [d/l]
