 +======String   ======
 +
 +====Description   ====
 +
 +The String class, part of the core as of version 0019, allows you to use and manipulate strings of text in more complex ways than [[arduino:data types:String| character arrays]] do. You can concatenate Strings, append to them, search for and replace substrings, and more.  It takes more memory than a simple character array, but it is also more useful. 
 +
 +For reference, character arrays are referred to as strings with a small s, and instances of the String class are referred to as Strings with a capital S.  Note that constant strings, specified in "double quotes" are treated as char arrays, not instances of the String class.
