Re: RPG enhancement suggestion

One of the reasons for Logical Files.  The other is setting up a key
for a file. In the SQL world there are VIEWs and INDEXs.  So don't be
afraid to set up a LF just to get a "limited" view of a file. Or just
use SQL and Create View to set it up for ya.  

We do this for our Employee Master file.  Some people need to be able
to view some of an employee's info.  The pay stuff and such stays 
'hidden' from this view.
