Re: Runaway NOMAX was: Is OS always to blame

From Al Macintyre whose AS/400 know-how could stand improvement

We have some known problems with programs that poorly designed, for which 
NOMAX is an easy out ... the programs do end eventually, and created 
humongous objects that we kill.  It might be smart if there was a tool to 
seek out & list all instances where we have NOMAX in our software, so that we 
can review which are prudent & which bear adjustment.
