Hi,
I need to create a file in foreach loop .
Its like in my code i need to manipulate data to appear in a certain way and its going through loops of foreach as shown below.

foreach $a(@a){
   foreach $b(@b){
       foreach $c(@c){
            foreach $d(@d){
                foreach $e(@e){
                                           print hash{$a}{$i}{name}
                                           print hash{$b}{$i}{name}
                                           .......
                                           if (){
                                           ........
                                           }
                                      }
                                  }
                          }
               }
       }

Now i need to create a file within loop @a so that i can access all the elements of @b for each $a.

Please help !

What should be in the file?  What are you doing with the file?  Do is it a different filename each time through the loop?

It looks like you are already accessing all the elements of @b for each $a, so I'm not sure where the file comes in,

I need to create a file for each element $b under $a. I need just one filehandler as only one file will be processed each time.
Illutrating it with a sample code to illustrate better-

foreach $a(@a){
¿   foreach $b(@b){
      for($x=0;$x<=20;$x++){
      open(fh,$nm.txt);
¿       foreach $c(@c){
¿            foreach $d(@d){¿
                foreach $e(@e){¿ 
                                          print hash{$a}{$i}{name}¿ 
                                          print hash{$b}{$i}{name}¿ 
                                          .......¿   
                                       if (){¿ 
                                         ........¿   
                                        }¿   
                                  }¿     
                             }¿     
                    }¿         
     }
      }¿       }

My dilemma is .. that the file name $nm actually needs to be the name of elements in $b. Say if @b = {apple,orage,grapes,kiwi} the file name that is generated should be apple.txt, orange.txt, grapes.txt, kiwi.txt .
 And the content of the files that is being written is print statements that are used to print the data out in certain format.
So it has to go into loop a, then into loop b, process data of loop c,d,e respectively, print it out in the files, which has names that of elements in array b.

open(fh,">$b.txt") or die "$b.txt $!";

 print fh $hash{$a}{$i}{name};
