Below is the info for the ADDN instruction from the V6R1 Information Centre:

Resultant Conditions:

/snip

Positive - The algebraic value of the numeric scalar sum operand is
positive.

Negative - The algebraic value of the numeric scalar sum operand is
negative.

Zero - The algebraic value of the numeric scalar sum operand is zero.

Unordered - The value assigned a floating-point sum operand is NaN.

/end-snip

I can't see the subtle difference you allude to - but that means very little
:-)

You're probably missing nothing at all! I was just surprised that the
QPRCRTPG API doesn't flag /MXD, /HI, /NOR, /TR or /ZC as an invalid
branch/indicator keyword for the ADDN(IS) statement - that's all. I was
expecting a more rigorous syntax check from QPRCRTPG.

Based on the documentation provided by IBM, the valid branch/indicator
tests
for ADDN are POS, NEG, ZER and UNOR - correct?

Ah, I see where you're coming from now. I did not check the docs AFA what
indics are available from ADDN, or might have followed. I am inclined to
agree with you, but now I wonder: is the documentation faulty or is the
fault with QPRCRTPG? Or maybe neither: does the doc say that those are the
valid flags after ADDN, or does it say that those are the ones that may be
affected? (See the subtle difference?)
