The government unveiled its latest report Friday on efforts to tackle the Year 2000 computer problem, saying the government and private sector are well on their way toward completing necessary tests and measures to avoid disaster.

Power companies had tested 85 percent of their important control systems by the end of last month, and that figure is expected to reach 95 percent by June and 98 percent by September, the report says.

In the telecommunications industry, tests on 69 percent of important systems have been finished, and 99 percent will be completed by the end of June.
