That's with a capital A0? Lower case a0 is numeric data in the syscalls and 
might be a name collision.

Could be. Whatever it is, its new and need integration. The name data sounds 
too generic though. Its got to be something more meaningful than data.

huh? That is new and doesn't seem right.

Yes, that has got to change. msg=has only one use and its the way it used to 
be.

We probably need a '-' added or a couple words rearranged. I need to hunt 
those down to see which way they should go.

That's not the issue to me, new and old are simply non-descriptive. New and
