Re: TEST(DE) with Numeric feild

[Scott Klement <klemscot@xxxxxxxxxxxx>]

Hmmm... I agree, this does not make sense.   However, I would've
expected ALL of your numeric tests to fail.

According to the ILE RPG Reference manual:

   If the character or numeric field specified as the field-name operand
   is longer than required by the format being tested, only the leftmost
   data is used. For example, if the dtz-format operand is *MDY for a test
   of a numeric date, only the leftmost 6 digits of the field-name operand
   are examined.

If that's true, the leftmost 12 digits of NUM1 are all zeroes, so all
the date tests should fail.

>From the information you're posting, however, it APPEARS that it's
actually checking the RIGHTMOST digits (as if you did a MOVE operation to
the correct size field)

Which, of course, is the opposite of what the documentation says... So
I'm curious as to what the explanation will be! :)
