have been resolved.
Mismatching error message is returned in *MISMATCH_DETAIL upon request,

of error message during the disassembling where error message is not
wanted. We avoid the dynamic construction of strings of error messages

are masked out to 0. As an example. op2 = 3, op1=2. CPENC would produce a
