It would really be nice if you gave a few examples of your position other
than opinions like

"the only world that doesn't agree with me is your world"

"Just speak your views somewhere else and see what happens"

Other than the fact that we can also use ISAM access when we choose, what
are we missing that other implementations of DB2 have that make a
difference in the business world?

I am working with legacy COBOL code lately and the programs that are
most understandable are the ones that use embedded SQL for their I/O
vs the standard muddle of start, read, write, rewrite. The seemingly
simple process of using a logical file in a program can be confusing
to the programmer who is looking a program for the first time. You
dont know what the based on physical is, the keyed order, if records
are selected or not, if there are multiple physical files in the
logical or not, what fields are included in the logical. With SQL,
all of that info is in the code. The traditional RPG pgm is almost
assembler like with its individual i/o, matching records of some kind,
lots of conditional code that selects and omits records, loads that
data into arrays, ...
