I'm sure that's quite possible. Graham

What have they contributed to world >wealth and wisdom? --- From: https://www.odci.gov/cia/publications/factbook/geos/is.html#Econ "Israel has a technologically advanced market economy with substantial government participation. It depends on imports of crude oil, grains, raw materials, and military equipment. Despite limited natural resources, Israel has intensively developed its agricultural and industrial sectors over the past 20 years. Israel imports substantial quantities of grain, but is largely self-sufficient in other agricultural products. Cut diamonds, high-technology equipment, and agricultural products (fruits and vegetables) are the leading exports. Israel usually posts sizable current account deficits, which are covered by large transfer payments from abroad and by foreign loans. Roughly half of the government's external debt is owed to the US, which is its major source of economic and military aid. The bitter Israeli-Palestinian conflict; difficulties in the high-technology, construction, and tourist sectors; and fiscal austerity in the face of growing inflation led to small declines in GDP in 2001 and 2002. The economy rebounded in 2003 and 2004, growing at a 4% rate each year, as the government tightened fiscal policy and implemented structural reforms to boost competition and efficiency in the markets. In 2005, rising consumer confidence, tourism, and foreign direct investment - as well as higher demand for Israeli exports - boosted GDP by 4.7%."

Classic typo. Hadn't even noticed it 'til you pointed it out. Graham

Ah, well, that's true, as far as it goes. The original provision, '.. to be reduced to 50 W after four years' was contrary to IEC rules, but was allowed into the standard somehow until it was challenged. There was a possible opportunity to change the bound in 1999, but it was not taken up. -- OOO - Own Opinions Only.

You're a bit slow to notice that, considering that the guys 'on your side' have been promoting death and destruction including nuking ppl ! And all I suggested was a slap round the face to someone who understands nothing else it seems. Hopefully it also illustrates I understand where a tougher response is appropriate too. Time to consider your sense of perspective I'd suggest. Graham |
