Rizwan, keeping in mind that I'm a USER of AIX, not a developer of it,
I'd suggest that programs built for 32 bit AIX will run fine on the new
machine, but with only 32 bit addressing. If the customer has need of
the larger address values, the code will have to be rebuilt with a 64
bit compiler. In general, a "rewrite" shouldn't be necessary, but that
depends on the code. For example, if the code assumes that int's and
long's are the same size, there will be some problems -- things like
that can cause trouble. I've been through it - it's not painless, but
it's not the end of the world, either!!
