Power2000 was a tool written in Delphi which assisted customers with PowerHouse applications to find all potential problems which may arise from the new millenium (remember all the scare stories in the late 20th century about disasters as a result of the millennium bug?)
It was essentially a global edit and change facility which could be programmed to find any syntax which may need to be changed because of date problems. It also came with a set of Impromptu reports. However, as you know, it is no longer supported.
Also, it was completely separate from PowerHouse and only ran on Windows.
However, it could be programmed to find any problem areas, not just problems relating to the millennium.
