I am mainly interested in bitwise operations (& | ! << >> etc) and comparisons (== <= >= !=), rather than arithmetic. By fast, I mean is it any slower (or even significantly slower) than the equivalent operations with 32 bit integers? I couldn't find anything in the docs or the FAQ; if I missed something, please point it out. Thanks for your help, and bye for now, -- Laurence Withers, mailto:lwithers AT lwithers DOT demon DOT co DOT uk Integrated Peripherals Operating System Project Leader || OPES Project Projects' homepage is at: http://www.lwithers.demon.co.uk/ Leader
