Dear Monks

I realize that my title is very bad but I couldn't think of a better one, sorry!
Anyway, I need to construct a string out of variables, like 
$str = $a.$b.$c.$d.$e.$f.$g etc $w.$x.$y.$z ;

[download]
Now, lets say $e is a 10 digit number representing the position inside this string of the word added by variable $x. However I only know $e when I've added $w(because I can calculate the length of the string)
So, if this is not clear enough, let me give an other example. 
$a = '' ;
$str = "blabla${a}blabla" ;
$a = "XXX" ;
print "$str\n" ;

Although I know that this examples doesn't do what I need, I would like it to print: blablaXXXblabla
Is something like this possible ?

Thanks a lot
Luca
