Hi all,

A colleague has an older Version of Mathematica (4.1) and cannot open
my notebooks.
I run Mathematica Version 7.
Is there a way to convert my Notebooks to make them compatible with
the lower version?

Thank you for your help!

If you convert your notebook into a .m file, it should be possible to
read it with Get in 4.1, but I am not sure if you can display it and cut
and paste it back into a 4.1 notebook. However, you could open the .m
file with a text editor and cut and paste from that into a 4.1 notebook.

Of course, having done that, you would have to make changes to eliminate
the use of any new functions, and you would have to remember that plots
were generated as a side-effect back then!

If you Save As... Mathematica Package (*.m) you will get an ASCII text
file that should be open-able in 4.1, although you will loose a lot of
Notebook formatting (all non-evaluatable cells will be (* comments
*) ). Your friend will have to hunt down syntax changes and re-code
newer functions to their older equivalents if possible. I am not sure
how 4.1 will handle the Unicode characters (like \[Alpha]), so there
may still be some work there. At least this will let him open the
file, though.
