/* HBTEST now reports 173 failures ( down from 376 ) many of the failures are justified.
I have tested this as much as I could, but since it invloved lots of "Cust & Pasets" more testing should be done.
It would be great if someone could review each of HBTEST Reported Failures on a one-by-one basis.
BTW, HBTEST reports 1 UN-RELEASED Memory Block (from before my changes)!
