Your question raises plenty of problems.

What exactly do you want to do? As the previous answers showed if you want to write to a file, then later on to read from it, you just need to close it in between. If you want to keep it open here is how you can do it:

#!/bin/perl -w
use strict;

open( NOTES, "+<note.txt")             # +< allows you to do read/writ
+e updates on the file
  or die "cannot open note.txt: $!";

print NOTES "stuff\n";                 # print stuff in your file

my $pos= tell NOTES;                   # mark the position before the 
+write you are interested in
print NOTES "test\n";                  # write your data (it should en
+d up with \n if you want 
                                       # <NOTES> to pick it up properl
+y later)

# when you are ready to read it

seek NOTES, $pos, 0;                   # reset filehandle to the right
+ position
my $fromfile=<NOTES>;                  # read
chomp $fromfile;                       # rememebr that \n? You might w
+ant to remove it now
if ($fromfile eq "test") {print "Yes, this works"}

Now why would you want to do this over storing the data in an array or something similar, which would be way faster than playing with files? I have no idea (size of the data you actually write?)
