I gave an example in another post. Summary: the argument value is check to be (say) numeric on function entry, if it is not numeric but can be converted to a number (eg it is a string of digits) then the convertion is done on function entry. If the value is used several times within the code (presumably as a number) then the type juggle 'string of digits -> number' will not need to be done since it was done on function entry. -- Alain Williams Linux Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
