This is arbitrary-bit data handling. It’s not a > “wrong approach”. So BIGINT on 32 bit platforms will be different to BIGINT on 64 bit platforms? BIGINT is a fix length number not a variable one ... -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
