I think the database will not be as good at handling the "B" data types.
The database does not have true integer support, it has RPGIII-style "B"
data types. Although, within RPG IV, you can use the EXTBININT keyword on
the Header spec to automatically convert the database "B" data types to "I"
data types in the program. Not sure if that helps or hinders overall
performance, however.

Subject: Considerations of converting a database of packed and zoned
numerics to integer types

I am curious about the "real" impact of converting our entire database of 
numeric data types to integer-like types.

I expect a noticeable performance benefit with the conversion of zoned to 
integer fields when they are part of the key simply because the keys will 
be much smaller to parse.  Packed to integer key conversion shouldn't have 
much of an impact at all.  I'm more interested in the areas of RPG like 
the MOVE command or any other commands that have special functionality.

Any thoughts?

Mark
