Hi Bill,

The "1111" error is what is called an "F-Line Instruction error".
It looks to me like the compiler thinks that there is a floating point
co-processor (i.e. mc 68881 or mc 68882) present. I believe
the default for Ultra-C is having the FPU enabled. Look in the OS-9 compiler
manual for instructions on how to disable FPU instructions.

(All FPU instructions start with 1111)
