Re: Max length of a VARYING field

Me, I think I'd rather have the compiler tell me I have a prototype mismatch
if I try to pass a small VARYING to a procedure that wants a large VARYING,
and maybe allow the STATIC keyword to auto-copy between them. I certainly
wouldn't want to pass different sized VARYING fields (even with the same
prefix size!) to a procedure if they were updateable -- without a length
parameter, you're just begging for trouble there, since the VARYING field
doesn't actually carry a maximum length, it's just a compiler artifact.


It's already possible to pass a varying parameter by reference to a procedure that wants a different length, but you have to specify OPTIONS(*VARSIZE). You would usually use operational descriptors to get the maximum size; you can use %LEN to get the current size.
