What is the purpose of the PAD?  The MPW Rez tool doesn't generate any
padding after the strings.  There is no harm in adding padding, however.


Second, a good call to use for this case (often overlooked) is Munger.
Munger operates on the bytes in a handle and can insert, delete, or replace
any sequence of bytes.  By using Munger you don't have to worry about
changing the handle size or moving bytes around (if you wanted to insert in
the middle).


Finally, one thing to watch out for is the fact that the individual strings
can start on an odd byte boundary.  I ran into this with my ApplicationMenu
INIT, since menus items are stored the same way.  You can't use a StringPtr
variable to point to one of the strings, since such a pointer needs to be
even.  (This is at least true in MPW Pascal.)
