I have a text file that contains lines of numbers. Is there a way to use array to call inside and return all + numbers and - numbers? Thanks for your help. I have a script that read the array I input, but I am wondering if this could be used to read array of numbers inside a text file. Thanks a million. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: 
 
use strict;

my @array = @ARGV ? @ARGV : qw( -1  1 7 -4 3 -51 4 47 -87); 



#******************************************
#\sorting the array from small to large
# HERE
@array = ( @array );
@array = sort { $a <=> $b } @array;

#******************************************
#\



my $sumAll=0;   
for (@array){   #\sum of all numbers HERE  sumAll
    $sumAll +=$_;
}




my $cur = my $best_start = my $best_end = my $cur_start = 0;
my $sumPos = $array[0];

for (0..$#array) {
  $cur += $array[$_];

  if ($sumPos < $cur) {
    $sumPos = $cur;
    $best_start = $cur_start;
    $best_end = $_;
  }

  if ($cur < 0) {
    $cur = 0;
    $cur_start = $_ + 1;
  }
}

my $sumNeg = $sumAll-$sumPos;     #\Sum of negative[sumNeg] = sumAll-s
+umPos



print qq(Start: $best_start 
End: $best_end 
Numbers: @array[$best_start..$best_end]\n\n

Order of Array: @array
Sum of All: $sumAll
Sum of positive: Chr1, $sumPos
Sum of Negative: Chr1, $sumNeg    

);

In my text file/data file, I have -1 1 7 -4 3 -51 4 47 -87 (randomly placed) top to bottom. So, it read as a column.
