RE: bug in MI-compiler

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

Leif:

I tried to make three points with my message.

1. conventional wisdom is only half right - it is conventional but
frequently not wise.  In the absence of "wise" the conventional part doesn't
matter.

2. I have frequently heard the "why would you want to do that" question.  I
have personally used it a few times when I didn't understand.  When I asked
it, I was trying to make fun of certain other people when they ask me that
question.  I think that you know what and who I mean here.

3. The smiley was (should have been) crooked.  Of course it shouldn't break.
Testing and the design of test plans is a long and painful process.  I would
have thought that your example would have been on someone's radar screen.
Perhaps it is now.

Is there some special reason for the two statement terminators on the
new-count declaration?

setting aside the "why", the translator shouldn't dump.
setting aside your smiley, the following program produces
the correctly rounded integer result '1':

DCL DD AVG-CHANGE BIN(4) UNSGND;
DCL DD NEW-COUNT  BIN(4) UNSGND INIT(3);;
DCL DD CHANGE  PKD(21,0) INIT(P'2');

DIV(R) AVG-CHANGE, CHANGE, NEW-COUNT;

a packed integer is still an integer.
This little piece of code gave me grief.
Just venting some of that.
