Hello netters,

We have made an iconic shell on top of windows 3.0, which is able to
activate windows and non-windows (dos) programs. To enable customization
of application activation we have made keyboard input redirections.
This kaeboard input redirection is implemented differently for windows
applications as for ms-dos applications. This is the reason we like to detect
the difference between ms-dos and windows executables.

In the MS-DOS Encyclopedia in appendix K we found a detection method
for new executable files ("MZ" on the first two bytes; on offset 3CH the
offset to the new executable header, which starts with "NE").

However a few days ago we found out that MS-Word for DOS has this same
strings and is a new executable file, but no windows applications!

Does anyone out there know whether a better mechanism exist to detect
the difference between a windows application and a ms-dos applications??

Thanks Theo
