Lets see.  10i0 can hold the integers from -2 billion (and change) to +2
billion (and change).  10u0 - yes unsigned - is 0 - 4 billion (and
change).  Depends on each C compiler as to what internal length
corresponds to how many bytes of storage.  I think int and long int are
the 10i0 on the iSeries.

short int can hold the integers from -32000 (and change) to +32000 (and
change), you can refer to it in RPG as 5i0.  unsigned short would be 0
to 64000 (and change), so 5u0 for it.

Sorry it's late and I'm too lazy to go find the actual exact limits. 
Try a search on google for MAXINT.  And I'm sure someone will correct me
if I am misremembering, it's been awhile.

Don't know, and haven't bothered to search it out.  Sorry.
