You didn't stop it (IEFUSI exit) and you didn't have enough paging
resources to support the virtual storage requirements.

"I hate a song that makes you think that you are not any good. I hate 
a song that makes you think that you are just born to lose. Bound to 
lose. No good to nobody. No good for nothing.

Because you are too old or too young or too fat or too slim too ugly 
or too this or too that. Songs that run you down or poke fun at you 
on account of your bad luck or hard traveling.

I am out to fight those songs to my very last breath of air and my last 
drop of blood. I am out to sing songs that will prove to you that this 
is your world and that if it has hit you pretty hard and knocked you for 
a dozen loops, no matter what color, what size you are, how you are built.

I am out to sing the songs that make you take pride in yourself and in 
your work."

Woody Guthrie
