Can you provide a (small) example of the text file you need to read in? Assuming it's one-value-per-line, it should just be a case of doing something like ...

my $number;

open FILE, "<", "/path/to/your/file" or die;
while ($number = <FILE>) { # read in a line of the file
  chomp $number;            # remove the newline

  # do something with each number

}
close FILE;

If it's more complicated than that (multiple numbers per line), then you can use a split on each line you read from the file to extract numbers one at a time.

Hope that helps ..
