I am trying to figure out a way of checking for the existence of a value in an array without iterating through the array.

I am reading a file for a parameter. I have a long list of parameters I do not want to deal with. I placed these unwanted parameters in an array @badparams.

I want to read a new parameter and if it does not exist in @badparams, process it. If it does exist in @badparams, go to the next read.
