rd48sec has asked for the wisdom of the Perl Monks concerning the following question:

I am new to PERL. I am trying to create a loop to print out several text files created by the eslif switch. Each line from the input files are evaluated and then put in an array "bucket". I am trying to print out each array bucket with:

bias.txt has b40, b20, b80 x.txt has x40, x20, x80 y.txt has y40, y20, y80 z.txt has z40, z20, z80

Any suggestions are welcom. Thanks for looking

@ARGV = ("-40.txt", "+20.txt", "+80.txt"); 
while (<>) { 
    ($null,$x,$y,$z,$xb,$yb,$zb,$tp,$f1,$f2) = split m!\+|\-|\s\+|\s\-
+|\s!;

    if ($f2 == undef){next;} #skip incomplete line
    elsif (($x<10) && ($y<10) && ($z<10)){ $axis[0] = "b";} # Bias
    elsif ($x>30){ $axis[1] = "x";} # X
    elsif ($y>30){ $axis[2] = "y";} # Y
    elsif ($z>30){ $axis[3] = "z";} # Z
# Temperature
    if (($tp<45) && ($tp>35)){$temp[0] = 40; $output[@axis][@temp] .= 
+$_;}    #-40
    elsif (($tp<25) && ($tp>15)){$temp[1] = 20; $output[@axis][@temp] 
+.= $_;} #+20
    elsif (($tp<85) && ($tp>75)){$temp[2] = 80; $output[@axis][@temp] 
+.= $_;} #+80
}

@file = qw(bias.txt x.txt y.txt z.txt);
foreach $filename (@file) {
    open $fh, '>', $filename;
    foreach $temp (@{$output[$temp]}) {
        print $fh $output[$temp][$axis], "\n";
        }
        $axis++;
}

Re: Printing out an Array of an Array...

    Can you provide a sample of the input date and explain what the output should be. In the meantime this is my guess at what you are trying to achieve.

    #!perl
use strict;
my $axis;
my %output;
while (<DATA>){ 
  my ($null,$x,$y,$z,$xb,$yb,$zb,$tp,$f1,$f2) = split ',',$_;
  next unless defined($f2) ; #skip incomplete line
  
  if (($x<10) && ($y<10) && ($z<10)){ 
    $axis = 'bias';
  } # Bias
  elsif ($x>30){ 
    $axis = "x";
  } # X
  elsif ($y>30){ 
    $axis = "y";
  } # Y
  elsif ($z>30){ 
    $axis = "z";
  } # Z
  else {
    next;
  }
# Temperature
  if (($tp<45) && ($tp>35)){
    $output{$axis}{40} .= $_;
  } #-40
  elsif (($tp<25) && ($tp>15)){
    $output{$axis}{20} .= $_;
  } #+20
  elsif (($tp<85) && ($tp>75)){
    $output{$axis}{80} .= $_;
  } #+80
}

foreach my $axis (sort keys %output) {
  open my $fh, '>', $axis.'.txt';
  print "Creating $axis.txt \n";
  foreach my $temp (sort keys %{$output{$axis}}) {
    print $fh $output{$axis}{$temp};
  }
}

#$null,$x,$y,$z,$xb,$yb,$zb,$tp,$f1,$f2
__DATA__

      Thank you so much!! You really helped me out. I am really close. The only thing that I need to get right is the order of each temperature in the file. Right now the "sort keys" puts the temperature order: 20, 40, 80. I need it to be 40, 20, 80.

      One line from input file is

      +00.28 +00.78 +00.36 +00.0 +00.0 +00.0 -40 20 43

      the -40 is the temperature

        Change this line

        #foreach my $temp (sort keys %{$output{$axis}}) {
foreach my $temp (40,20,80) {
