AppendTo
 Usage
• AppendTo[s, elem] appends elem to the value of s, and resets s to the result.
Notes
• AppendTo[s, elem] is equivalent to s = Append[s, elem]. • AppendTo[s, elem] does not evaluate s. • You can use AppendTo repeatedly to build up a list, though Sow and Reap will usually be more efficient. • AppendTo works on SparseArray objects, returning ordinary lists if necessary. • New in Version 1.
