I have tried with both the 6809 and 6309 versions of NOS-9 L2, and both systems hang when I try to run a Basic09 I-Code program from the command line with no parameters when it is expecting a parameter.

The documentation for NitrOS-9 that came with the Northern Exposure package states:
"Basic09 and RunB
Without patching, the BREAK and Shift-BREAK keys become inoperative. These 
patches modify the register stack offsets in Basic09 and RunB."

Patched versions of Basic09 and RunB were supplied. The current versions 
supplied with the Sourceforge NitrOS-9 work correctly with BREAK. They also work 
correctly with the PARAM statement.

You may need to post some code to get good answers.
