I need to make four hash in one file, for one hash it works well, I want to make a sub create_hash, it can not give me any output.I have no idea how to make it. Please help! Thanks. In main part, it works: <BR<#Create hash


#Open the output file
my $outputfile="myhash";
unless( open(MYHASH, ">$outputfile")){
print "Can't open file \"$outputfile\" to write to!\n";
  exit;}


#Create hash keys and values array
my %myhash=();
#I use mydnahash' values to be myhash's values
@myhash{@reg_data}=@mydnahash{@reg_data};


#Create hash
while(($k, $v)=each %myhash){
  print MYHASH "$k=>$v, "};

I have to repeat it four times do the same thing, so I want to create a sub hash,how can I make this kind of sub? Thank you!
