Re: RPG overloading (was RPGV?)

As far as numeric fields, yes, it could be transparent... but I guess I
was thinking more of the bigger picture. For alpha fields, I
frequently pass more data than the length of the field on the prototype,
and I've run into several others who do the same thing.

My concern is that the RPG compiler would see that my field size doesn't
match, and go through a temporary intermediary -- which would cause the
data to get chopped off.

But as I'm thinking about this a little more, I'm not sure that would
really be an issue. I probably spoke too soon.

I wondered the same thing but then I considered that a move or eval to a smaller field will truncate so perhaps this is not so different.

Do you mean the prototype has OPTIONS(*VARSIZE) specified? Or just that you pass a larger variable than the prototype says is allowed? Can't say I've noticed that the compiler accepts that.

As always, even with the "protection" afforded by prototyping the programmer has to be careful and know what they're doing.
