I have a script that needs to take @ARGS or the "<" redirect.

%perl script.pl 7 12 5

or

%perl script.pl < text.txt #where the contents of the text file are 7 
+12 5

If there aren't @ARGS or a "< text.txt" I need it to print a message saying "use args or <".

I think I'm on the right track but I can't really get it to work.

Here's my code:
if(@ARGV)
{ my @node_numbers= @ARGV}
else
{ my @node_numbers = do { local $/; split ' ', <> };}

if (!@node_numbers) 
{
print <<"EOF";
#####################################
#
#  use args or < a text file
# 
#####################################
EOF
die;
}

# Do rest of code after here using @node_numbers
