The command to help you do this is :execute, which can be
abbreviated to :exe. See
:help :execute
For example, your two commands above could be written as
exe "source " . yyy . "\aaa.vim"
exe "set xxxdir=" . yyy
Since the backslash (\) is also used to escape or quote the
character following, you may have to use \\ instead of just \ or
enclose the string containing \ in single-quotes (') instead of
double-quotes ("). (I didn't test the first command to see.) It is
often safest to use forward slashes (/) instead of backslashes to
separate directories in a path, even when using Vim on Windows. Vim
knows how to translate them to backslashes before giving the string
to a Windows command and you avoid the quoting issues.
An alternative way to set Vim options is to use :let instead of
:set, as described here:
:help :let-&
Your second command could then be written as
let &xxxdir = yyy
