I forgot to ask - in regard to a file I would like to have!

Since PUTR is designed for a DOS environment, it will
(or so I understand) create (the actual command is
FORMAT) files with a maximum size of 2 GBytes
minus one cluster size. Since I am using a FAT32
system, I understand that I am allowed a file of a
maximum of 4 GBytes minus one cluster size.

Obviously, that is TOO large to download, but when
I did a Zip, the compressed file was on 2 MBytes.
Even better, when I used bzip2.exe, the compressed
file was just over 1500 bytes. The example I used
was a file with all zeros that was 2,147,450,880 bytes
which was Zipped to 2,084,166 bytes. When I
used bzip2.exe, the file was ONLY 1518 bytes.

What I wish to have is a file that is all zeros and is
exactly 2,147,483,648 bytes. I imagine that a
Zipped file should also be about 2 MBytes and that
a file compressed with bzip2 would be about 1500
bytes. Obviously a FAT32 file system is required.

Thank you in advance to anyone who can help!
I an an RT-11 addict and I want to spend my time
with that operating system.

Sincerely yours,

Jerome Fine
