FYI. This test is incomplete/erroneous. The valid characters for modern

Ed, thanks for the clarification (x'00'). What about on real 3270
terminals. Will x'00' cause a program check?
No. From the very beginning, x'00' was defined as the "null" character.
An input field containing trailing nulls can be shifted right with
insert. Trailing blanks cannot be shifted. This difference in behavior
is the reason for the ISPF editor NULLS command. In an output field,
there is no substantive difference.
