Okay - now maybe this is a stupid question but:
Why do arrays get passed by value, whereas structs get passed by reference?
Because that's how CF has always done it... I bet it was originally an
accident in JJ's C++ implementation but then code began to rely on it
and the behavior has to be preserved. Anyone got a really old copy of
CF that supports both arrays and structs to see what the assignment
behavior was?
After a quick dash to our museum and digging out our really, really old
copies I remember that Structures came in with CF4. Before that
everything was passed by value. I suspect (and remeber rumours at the
time) that structures-by-value were just too hard so from that point we
had the mixture of both pass-by-value and pass-by-reference. Similarly
we had the oddity of the StructCopy function being half and half, now
that was a bit wierd.....
HTH,
