By that argument every program you write alters the software environment
and potentially violates your licence. IBM sells you a computer with a
licensed software environment that allows, nay demands, that you write your
own programs or at least buy programs from someone else. If I write a
program that monitors activity and changes run priorities and pool sizes on
the fly IBM is perfectly happy, and if I happen to use undocumented
features, well that's my own look out. Where is the dividing line between
that and changing the attributes of a job that uses the 5250 data stream?
