I wouldn't agree with you and you definition of IsDefined, IsDefined checks
to see if a variable is there, if it is True, if it isn't False.

In your dictionary example; use isdefined to see if the word is in the
dictionary and then if it IS there, view the definition if it ISN'T, send
them to Websters website to ask that it be added :)

> <input type="checkbox"
