I have tried to write a nsh script that...
* Runs an application.
* Examines the application's return code.
* Then runs one of several applications based upon the value of the return code.

The application return code seems to have an effect on $?, if I set the return 
code to 0 or 1,
but if I set the return code to 2, $? never shows the 2.

How can I store the application return code in a local nsh variable, so I can 
test it using if-then-else-fi?

Regards,
Bob
