AppendTo
AppendTo[
s
,
elem
] appends elem to the value of s, and resets s to the result.
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.
An alternative and often more efficient way to build up a list is to use a sequence of assignments of the form s
=
s
,
elem
 , and then to call Flatten on the resulting structure.
See the Mathematica book: Section 2.4.4.

Further Examples
This defines a list.
In[1]:= 
Out[1]= 
This appends the number  to the end of the list.
In[2]:= 
Out[2]= 
The original list is changed as a side effect.
In[3]:= 
Out[3]= 
On the other hand, Append does not change the new version of the list.
In[4]:= 
Out[4]= 
In[5]:= 
Out[5]= 
In[6]:=
