This'll work, put the numeral in the right place, and actually compensate for my not reading the File::Basename pod all the way through (I had already sent a reply to Pete, then I looked over the code afterwards, and realized I'd made a mistake in the example):

#!perl
use strict;
use File::Basename;

my $i = 1;
my $newfile;
my $filename = "harddisk:desktop folder:example.html";

fileparse_set_fs_type("MacOS");

my ($base, $path, $suffix)  = fileparse($filename, qw(.html));

do {
    $newfile = "$path:${base}_" . $i++ . "$suffix";
} while(-e $newfile);


I did notice that the pod says you need to call fileparse_set_fs_type as above or it'll default to Unix pathsep syntax, yet the code above runs fine with or without it.
