“We don’t know, man, we just don’t know.” The confident Nick of months
prior shook now, leading Fred to his cubicle. “We coded the application. We
debugged until it compiled without errors. When we run it- core dump!” He
threw up his hands, then dropped into his swivel chair. “We’ve been
pestering IBM support, but they haven’t been very helpful.”
“Well, why would they be?” Fred frowned, pausing at the cube threshold. “I

“Nothing’s wrong with it. It compiles!”
“So? It could still have errors.”
Nick swiveled around to face him. “Dude. It compiles.”
