in reply to Adding Files in a directory to an array

Yeah, you can't do that, because Perl gets confused between the globbing operator (<*.txt>) and the file input operator (<FILE>).

The way to do it it to use the glob function instead.

$searchcontacts = "cd32/*.cd"; @allcontacts = glob($searchcontacts);

    Not exactly.

    While it is better (and I mean really, really better) to use the functional glob, you still can force perl to interpolate variables. Actually, only filehandles and simple scalars are not interpolated (see perlop). So these:

    @dir=<$hash{$key}>; @dir=<$array[0]>; @dir=<$object->method>; @dir=<${foo}>; # and even @dir=<$structure{'filehandle'}>;
    are interpreted as globs. Note that this is a caveat in the last case! Since you probably want the <> to do a readline in the last case, people really need to be aware that nested structures are always globbed. Only simple, straightforward variables like $foo result in readlines.
