I completly agree with you. That is exactly how I used it, too. However it would have been nice, if IBM had implemented an alternative SELCT likt the Java CASE as explained by Mark Murphy in his first message.

Betreff: RE: IF..ELSEIF vs SELECT
I personally use them both and distinguish between them (even though they
can be used alternatively).
SELECT is used if I have a condition which results in multiple different
When FieldA = 1;
When FieldB = 2;
If / ElseIf is used if I have more complex or different conditions which
have to be checked one after the other:
If Field1 = 'A' and ( Field2 > 5 or Field2 < *Zeros;
ElseIf Field1 = 'B' and Field3 < 100;

Oooooh - you've started something now! Before long we'll have full-on war
over DoW vs. DoU!! <grin>
There is no difference between the two constructs, John. SELECT pre-dates
ELSEIF. Which you use is purely personal taste. I suspect the ELSEIF was
added later to recognise that many programmers coming to the IBM i platform
(and RPG IV) were more familiar with IF/ELSEIF/ELSE/ENDIF. Barbara Morris
may be able to provide a little more insight.

Could anybody shed some light on when to use IF..ELSEIF and SELECT.
Seems to me that the semantics of SELECT is exactly the same as
SELECT just takes one line more (the SELECT).
