As I recall, this is working as designed.  Traditionally, RPG was very
forgiving of numeric overflow, and did not enforce any restrictions on
numeric operations.  Remember the old date format conversion trick (USADATE
Mult 10000.0001 ISODATE)?  The EVAL opcode brought runtime detection of
overflow conditions.

If you were to use Eval instead of Z-ADD, then you would get an error at
runtime.

Subject: Overflow diagnostic messages



The following are a few lines in one RPGLE pgm.

C               Z-ADD     30157.39      VAR1              7 2
C               ....
C               Z-ADD     VAR1          VAR2              7 3

Overflow would occur as per the above code. The compilation option
TRUNCNBR was set to *NO. I did not see any diagnostic messages in the
compiler report. Am I missing something?

Is there any way to see, where are the lines, in which, overflow might
occur?

TIA,
Murugesh.
