The rgexp argument is a Regular expression object. It can be a variable name or a literal.

{
  var s1;
  // Test string for existence of regular expression.
  if (re.test(s))
    s1 = " contains ";
  else
    s1 = " does not contain ";
  // Get the text of the regular expression itself.
  return(s + s1 + re.source);
}
