Hi John
I think you need to tell us something more. You say you
my @parts = ("one", "two", "three");
substr($parts[1],0,0) = ".";
print "@parts";
works fine. (Unless you really /did/ miss the closing quote from 'three'?).
May we see a little more of your code?
Don't forget that, if $name doesn't contain any '.'s then $parts[1] _will_ be
uninitialized.
Cheers,
Rob
