I have two files namely ICD-Codes-text which is tab format and other file named female.txt which has been split word by word . i need to compare the contents of female1.txt to ICD-codes file 0th array values. If there is a match then the matched value in female1.txt should be replaced with ICD-code files corresponding 1st array value. I am a beginner in PERL. I tried to write some code but i do not know where am going wrong or its completely wrong. Help me with this please

#!/usr/bin/perl

print "reading 'ansvarig_vardenhet_utf8.txt'\n";
open(WIN, "icd-10-codes.txt");
while($line = <WIN>) {
  @columns = split(/\t/, $line);
  #print "$columns[1]"; 
  foreach my $value (@columns) {
    #print "$value\n"
}
}
close(WIN);

print "reading 'ansvarig_vardenhet_utf8.txt'\n";
open(IN, "female1.txt");
while($line = <IN>) {
  %col = split(/ /, $line);
  #print "$columns[1]\n"; 
  foreach my $val (%col) {
      if($val == $columns[0]){
         $val =~ s/$val/$columns[1]/g;
         print IN ">>$val\n";
        }
      }   
}
close(IN);

Please look at how your file samples appear to the rest of us; with no line breaks, we cannot tell what should be on line one of the file, vs line two, etc.

Then, please edit your post so that lines of data do not all run together.

If you cannot edit the post, (because you did not log in when you posted it), then add another post with just the two data files.

When you post anything on this site, there is a notice, in bold, directly below the "preview" button:

Put <code> </code> tags around your code and data!

(The notice does not appear then you edit an existing post, but probably *should* appear.)

We want to help you. You just are not giving us all the information we need to help you.
