Re: Overflow errors on add

[eric.delong@xxxxxxxxxxxxxxxxx]

     There is a command line option TRUNCNBR in the CRTBNDRPG command. 
     This will cause overflow values to be truncated. This doesn't work 
     on calculations performed within expressions (eval and other 
     opcodes that us the extended factor 2 field). In cases where you 
     know you'll have an overflow occur, just go back to the standard 
     math ops in place of the expression calcs.

Hi,
I am in the process of converting my source from RPG3 to RPG4 and have the 
following piece of code.
     
RPG3
add x   y
     
which translates to
RPG4
eval    x = x + y
     
Now RPG3 is forgiving of overflow errors, but RPG4 is not. 
How can I trap potential overflow errors?
Can I set a compiler option (in CRTBNDRPG) to show this condition? 
Euan.
