Are you sure you want a hash? The whole point of a hash is to create an
array with custom indexes instead of consecutive numbers.
In any case, I think what you are looking for is readdir(). This will
return an array with the files in a directory. The following code will
populate the @files array with the contents of the mydir directory.
opendir(DIR,"mydir");
@files = readdir(DIR);

Try map:
%hashtable = map { $ctr++, $_ } @files;
Or even:
%hashtable = map { $ctr++, $_ } <*>;
Of course, I've probably got the syntax wrong - since I
don't use map that often. You can, of course, write many
programs in terms of sub/map like:
sub add {
return map {
#do processing
} @_;
}
which can really annoy your coworkers.
