sequential file formats

I have noticed that every compiler/op sys seems to create a different
format for sequential files. for instance, a COBOL program on the
mainframe will create a sequential file with a four byte header that
indicates length. On microfocus on AIX, a COBOL program will create a
similar file but the with a special record as the first record that has
some additional information.

Does anyone know of a comprehensive list of all the different formats
that may be out there?

I will post small sample program that will create a two record
sequential file in hopes that some of you will run the program and
report back the format of the file that is produced. A hex dump as a
post would be great. if you can not hex dump on your selected
operating system, then email the output to theador@@@@gmail and I will
hex dump the file and post it.

Hopefully we can cover these combinations:
Fujitsu on UNIX
Fujitsu on WIndows
IBM on AIX
IBM on z/OS
MicroFocus on UNIX
MicroFocus on WIndows
AccuCOBOL
OpenCOBOL

Thanks to those who can help in this experiment,
Theador.
