What does "rob his hank" mean? from Joyce's The Painful Case

"He allowed himself to think that in certain circumstances he would rob his hank but, as these circumstances never arose, his life rolled on . . ."

What does this expresssion mean?

Thanks,

Andy

Well, I´ll beg your pardon, but this is obviously and simply a printing error - and I´ve confirm it - in my version of this story (in The Essential James Joyce, Penguin Books, 1963, p.426) that sentence reads:

"He allowed himself to think that in certain circumstances he would rob his bank but, as these circumstances never arose, his life rolled out evenly - an adventureless tale."
