Re: Overflow values

Hi Rajeev!  That won't work since numeric overflow is
always signalled for numeric expressions.  TRUNCNBR(*YES)
is offered only for compatibility with older programs.
Truncation is an option only for the fixed-form arithmetic
ops and only for the decimal numeric data types: packed,
zoned, and binary.

For various reasons, numeric overflow is always signalled
for newer features, such as expressions and the integer
data types.

BTW, if you get an unexpected numeric overflow exception
in your program, never, Never, NEVER fix it by changing
TRUNCNBR(*NO) to TRUNCNBR(*YES).  If the program was
compiled with *NO, it was for a reason.  That reason was
to help you discover bugs in your program.  TRUNCNBR(*YES)
may get rid of the numeric overflow exception, but you'll
then have an even bigger job ahead of you to fix the errors
that show up in your program.  The worst case is that you
won't see a problem, but your customers will get incorrect
bills!

Cheers!  Hans
