Hi all,
Why can't I use a subscript in the angle brackets? e.g.
@files=`ls /app2/koekemtn/scripts/dbstats/test`;
chomp $files[0];
open ( $files[0] , $files[0]) || die Cannot open $files[0]\n;
while ($files[0]) {
print $_;
}
TIA

Thanks for the help. So I cannot use an array or hash in angle
brackets as file handle. I have a variable amount of files which I'd
like opened and the contents shuffled. What would be the best way to
do this as my next idea also did not work?

@files=`ls

(+0200) typed the following:
TK $file$num = $line; # Problem assignment!
use hash instead scalar variables; $file{$num} is OK.
First you have to ofcourse declare it: my %file = ();

foreach my $file ( @ARGV ){
if( my $fh = new IO::File $file ){
# Be explicit[1]
if (my $fh = IO::File-new($file)) {
push @infh, $fh;
} else {
die Failed to open input file '$file': $!;
}
