Hey all- here is the code... it is pretty sloppy i am sure, but it is also my first time. Perl is still very new to me.

#!/usr/bin/perl -w
print "What is input file name?: ";
    chomp($input = <STDIN>);
print "What is output file name: ";
    chomp($output = <STDIN>);
print "What is the mininum magnitude?:";
chomp($min_mag = <STDIN>);
print "What is maximum magnitude?:";
chomp($max_mag = <STDIN>);


open (INPUT, "$input") || die "died opening input\n";#opening up ngc18
+8cata and putting it into INPUT#

open (STDOUT, ">$output") || die "died opening output\n"; #opening up 
+ngc188cat2 and setting output of out#

$cfo = "O";
$status = "STATUS=OK";

open OUT, "+<holder";

while ($inline = <INPUT>) {
 #INPUT defined as variable#
 @mag = split(/\s+/, $inline); #firstline of array defined by split of
+ white space into variable inline#


if ($mag[12] >= $min_mag  && $mag[12] <= $max_mag) {
     print OUT "$inline"; #printing to OUT 
}
}

close OUT;
open NEW, "+<holder";

while ($sep = <NEW>) {
     @firstline = split(/\s+/, $sep);

$hms1 = $firstline[2];
$rah2 = ($hms1 / 15);
 $rah3 = int($rah2);

$ram1 = ( abs($rah2 - $rah3) )* 60;
$ram2 = int($ram1);

$ras1 = abs($ram1 - $ram2) * 60;
     $ras2 = sprintf "%-02.3f", $ras1;
############################################ 
 $hms2 = $firstline[3];
 $hh2 = sprintf "%1d", ($hms2);
 $mm2 = sprintf "%02d", (60*( abs($hms2) - abs($hh2) ) );
 $ss2 = sprintf "%-02.2f", 3600*abs($hms2) - 3600*abs($hh2) - 60*abs($
+mm2);
############################################################
$obid = "NGC 188 - $firstline[1]";    

###########################################################
 
 
 write; #writing to STDOUT
} 

close INPUT;
close NEW;


format STDOUT = 
@>>> @<<<<<<<<<<<<<<<<<<< @> @> @>>>>>  @< @< @>>>> @  @<<<<<<<<      
$firstline[1], $obid, $rah3, $ram2, $ras2, $hh2, $mm2, $ss2, $cfo, $st
+atus,

Just to explain how i thought about this. The information is ran through the first loop, containing the "if" statement, which takes out the information I want. From there, that information is put into a seperate external file. That external file is then opened and ran through a second loop, which gives me the information i need, that is subsquently formatted into a data report.

So what i am wondering is how i can clean up the loops, or if it is possible and easy combine the two loops that I have in order to make just one loop? I would perfer to not have an external file ("holder") if at all possible. I would appericate some help, because I am going to have to make some more if loops like this, asking to examine different elements in the original dataset instead.

Thank you! srkaeppler
