Subject: A quetion about ruby string

How can I change a string to regular expression? Take this method for an
example:

def match(pattern)
   ...
end

This method accepts one parameter as a regular expression pattern, when
I invoke this method by

match(/.../)

it works fine. But if I invoke this method by

param="/.../"
match(param)

it doesn't work as expected. It seems that the string is different with
the regular expression. If the pattern stored in a string variable, how
can I use it?

thanks.
