ARITRAP (NM) 
(changed) 

The trapstate parameter of the NM version of the ARITRAP intrinsic is a
required 32-bit signed integer passed by value.  The parameter size has
been expanded to handle the additional arithmetic traps available to NM
applications.  The trapstate parameter represents a value enabling or
disabling arithmetic traps.  (An exception is the IEEE Inexact Result
trap, which can only be disabled.)

The CM version of ARITRAP performs as described in the MPE V/E Intrinsics 
Reference Manual (32033-90007).  The NM version performs as described in
the MPE XL Intrinsics Reference Manual (32650-90028)
