Re: [EXTERNAL] Re: Expanding a field in a file or adding a new field to the file

Hi Rob

I think the idea is to have an index of the same name as the original PF, with the same format level ID - that index is going to be created over a rename of the original PF.

Then there is no need to recreate any programs using that file "name".

We saw a similar technique when looking at using Unicode in our tables.

And you'd need to convince any CMS not to check this dependency, right?

I think I have it right - others doing modernization can leap into the circle and comment further, please!

I don't understand.
