I missed the point here... the zone files are different in that example!!

I've built a better model than the one at Data General
For data bases vegetable, animal, and mineral
My OS handles CPUs with multiplexed duality;
My PL/1 compiler shows impressive functionality.
My storage system's better than magnetic core polarity,
You never have to bother checking out a bit for parity;
There isn't any reason to install non-static floor matting;
My disk drive has capacity for variable formatting.

I feel compelled to mention what I know to be a gloating point:
There's lots of room in memory for variables floating-point,
Which shows for input vegetable, animal, and mineral
I've built a better model than the one at Data General.
