Datasets with NUMS/PACK ON

I've been around for a long time, and I honestly don't know the answer to this: when is it ever preferable to have a dataset defined with NUMS ON? or with PACK ON?

I would say never...

but everything has exceptions,
as far as number on there might be standards to follow,

as far as pack that a no
the main issue is that the packing is transparent under ISPF
and You realize that something is wrong only when You use the thing as sysin for example

so my advice is no no to both questions

Well, with all of the questions we see on these, I've been curious as to why the Sysprog's and/or Storage Admin's are creating datasets or dataset profiles with these attributes enabled?

Hello,

I suspect that newbies (and some not-so-newbies) are cloning old existing datasets and don't even know they've "specified" these atributes. Realization comes when they "get bitten".
