I did some work for a large financial company, writing a compiler for a query language that had been compiled and interpreted by COBOL programs. I got a BIG speedup, enough to secure some new contracts. They (the UK office) then asked me to implement it on another kind of machine. We discovered that the US parent office (in Boston, I think) had declared that the Brits were wasting their time and it couldn't be done. The UK guy had faith in me. And we got a massive speedup there too. -- Using UNIX since v6 (1975)... Use the BIG mirror service in the UK: http://www.mirrorservice.org
