Sets or gets the number of limit test failures
until limit test aborts. 0 runs the limit test
until aborted, n stops the limit test upon the
n
th
failure.

LimitClear
bo
0 or 1
Clears limit test statistics; this will also reset
the count for limit number abort. A transition
from 0 to 1 causes the clear, after which the
value returns to 0
