Thanks for clearing that up... I've not used cobol on the -11.

I figured it was like other optional instruction sets with
regards to layered products... like Basic, which comes in
the NHD (no hardware), EIS (for machines with EIS) and FPU
(for machines with FPU). The problem is when you run the EIS
or FPU version on a machine which doesn't have the required
hardware... it doesn't work. NHD will work everywhere since
the code it generates uses the basic pdp-11 instruction set.
