When the data step sets in E2004.&model._ALL_ it is setting in all datasets in the "E2004.&model"  library so the where statement will apply to all the observations in the concatenated file. Obviously they should all have the variables required for the where condition.

What I have read about macros did not clarified this name: _ALL.
I assume this is macro convention…
I look at the EC folder’s staff and found multiple files overthere…..

Does it means that _ALL refers to each of the file name under EC folder?
Does it means that WHERE condition will fork for each of 20 files under EC folder?

Thank you in advance,

Irin
