Re: definintion of signed integer?

I am guessing but one part of the equation is an unsigned integer and minus
21. My guess is that it is seeing the unsigned integer and deciding the
output of the equation is an unsigned integer then converting it to a signed
integer but never gets that far.

I would either try making the Positive value as signed or try a
%Int(PositiveValue - 21).

I have a variable defined "3i 0", local to a subprocedure that I expect

minus 18 into the field, I get the dreaded "MCH1216 - too small to hold
result" crash & burn.

I'm sure I can fix it instantly by defining packed numerics, but I need
to understand the rules.

D PositiveValue 3u 0
D NegativeValue 3i 0
/free
PositiveValue = 3;
NegativeValue = PositiveValue - 21;
[down in flames we go]
/end-free

What could be so tough about subtracting 3 from 21 and expecting -18?
Please set me straight here. It's an SQLRPGLE program on a 6.1 box.

Many thanks.
