From: Colin Summers Date: 2007-06-16T05:36:05+09:00 Subject: test to see if a variable exists So I am stealing all these identities and storing everything in a big array of objects stolen_identity, and having the index be social security numbers: ss[34323843] = Stolen_identity.new But say I pick up a paycheck stub and it has 3428294. How do I know if I already have it? Does if (exist ss[3428294]) then ... end work? How can I see if a variable exists? Thanks. (please include your social security with your answer)
