in reply to Variable blasphemy

This: @tmpConv[0] should be this: $tmpConv[0]. (If you had use warnings, it would have told you that.)

You use @array to refer to the whole array, and $array[i] to refer to the individual scalars it contains.

Whether that will fix your problem I haven't checked, but its a good start.

    Updated the code in the original post and added the "use warnings". Same output problems though. No warnings given. Sigh.

      Are you reading a windows file on a unix machine ?
      Try changing chomp to s/\s+$//g;
      Update:

      Assuming each RSno has only one StarName and vice versa, it would be simpler to use a hash for the conversion

      #!perl
use strict;
my @Stars = qw(CYP2C19_10 CYP2C19_12); 
return if (@Stars == 0);

# name,no
my $ref_file = "test.csv";
open my $star_FH,'<',$ref_file
   or die "Could not find reference file $ref_file : $!";

my %RSno=();
my $count=0;
print "Reading from ref_file $ref_file .. ";
while (<$star_FH>){      
  s/\s+$//;
  my ($no,$name) = split ",",$_;
  $RSno{$name}   = $no;
  ++$count;
}
close $star_FH;
print "$count records read\n";

for my $StarIndex (@Stars){
  if (exists $RSno{$StarIndex}){
    print "$StarIndex is $RSno{$StarIndex}\n";
  } else {
    print "$StarIndex NO CONVERSION\n";
  }
}

        That worked! Thanks! Can you explain what the difference was (and what the above code means?) =P Thank you so much!

        The csv file was saved under windows, yes. Do I need to open it a different way?
