ASCII
dec = 255 hex = FF name = EO (end of)
sometimes refered to as phantom space

EDCDIC
dec = 55  hex = 37 name = EOT (end of txt/transmit)

or IBM
dec = 3    hex = 03 name = ETX (end of txt)

etc..etc.. BS

There are alot of real easy ways to do what I think
your trying to do, the easiest being.

seek to the end of the file, grab the length of the file (in bytes) and
store the length value in the file

i.e: {{{3}123},{{4}1234}}

I want to help, so give me an example.
