Uhm, the same way as you do in non-binary files? If the file
is small: open the file read/write, read in the file (in a scalar), insert "+" wherever you want it,
seek back to the beginning of the file, write the scalar,
close the file. If the file is large, open a temporary file
for writing, open the original file for reading, read from
the file up to the point where you want to insert the "+"
while writing what you've read (in chunks) to the temporary
file, write "+" to temporary file, read rest of file while
writing it to the temporary file, close both files, move
temporary file to original file.

If you do it on Windows, you have to use binmode on the file handle.

Not using windows for anything but games/shell windows to other systems and Office apps I've always been curious as to why this is the case. It seems odd to me that an OS would care what kind of file you are opening.

Always use binmode and you'll never get bit by this on
any of the platforms it matters (windows is just one).
