Sequence objects are fine, if you are not compiling to v5r1 :-)

But they can't handle yes/no (ja/nein) kinds of things or other textual options. And that is what we use data areas for - to allow customers to customize the behavior of our products. Examples include which PDF conversion program to use - we have different ones.

Another reason to use data areas is to avoid adding parameters to programs. This helps to maintain backward compatibility in our products - so that customer's code does not break.

Instead of using an data area, I use an SQL sequence object (which is
nothing else than a data area).

In an sequence object a couple (depending on the cache you defined) of next
numbers are in the pipeline and you do not have to determine the next number
by yourself.
The next number is retrieved simply by requesting the next one:

Exec SQL Set :MyNxtNo = Next Value for :MySequence;

I like that idea.
