Those would fail the "lower" bound c'SMITH '. However, with the blank
(x'40') in the sixth position of the "lower bound" specification, any
"printable" EBCDIC character would qualify provided the first five
positions were greater or equal to c'SMITH'. Thus the "lower bound"
indeed has a hole in it.
