Re: DOU/DOW for READ Loops

Jim,

As always, there are pros and cons.  When we moved from the S/36 to the
AS/400, we had a sort of internal religious war over internal vs. external
(I was somewhere in the middle, could see advantages as well as
disadvantages).  The outcome was that the existing applications stuck to
internal descriptions and that a new application would be built using
external descriptions.  I was one of the developers of this new application;
now I am technically responsible for this application.  A few years ago, I
decided to convert this application to internal descriptions, for the
reasons I wrote (and one more reason: our programmers are used to using
internal descriptions).

We would love to use externally described files, if only we would be able to
explicitly name the fields we want (like it is possible in the output
specs).  Who uses 'SELECT *' in embedded SQL?  In SQL it is common practice
to name the fields you want.
