Hi all,

I need to write a script which would carry tar.gz archive in itself, which upon running it will save to a file on filesystem.

This script will be run under Windows environment.

I've decided to use __DATA__ section in order to store file contents.

However, I cannot later read the whole contents. File which I write is binary (tried both .dll and .tar.gz), and both contain SUB symbol (Notepad++ shows it that way). As I understand, it is equal to Ctrl^Z, and perl treats it as EOF and stops reading rest of the DATA.

But I need the whole data to be read and written to file. Any ideas how that can be accomplished?

Here is sample code (I already tried like 20-30 different ways, all with the same result): 


my $outfile = "$HF_DIR/binary_copy.dat";
open (OUTFILE, ">", $outfile) or die "Not able to open the file for wr
+iting. \n";
binmode (OUTFILE);
binmode(DATA);
do { local $/; print OUTFILE <DATA>;} ;

close (DATA) or die "Not able to close the file: DATA \n";
close (OUTFILE) or die "Not able to close the file: $outfile \n";

and at the end there is __DATA__ section, with all the binary data: 

__DATA__
..binary data....SUB character......binary data...
......

[download]

So, perl only reads and writes til the first SUB character. And I need it to read and write all of the data.

Any help would be very much appreciated! Thank you in advance...

UPDATE: I decided to use base64 encryption and now all works, thanks for all your help guys!
