Simple financial package

A novice programmer was once assigned to code a simple financial package.

The novice worked furiously for many days, but when his master reviewed his program, he discovered that it contained a screen editor, a set of generalized graphics routines, an artificial intelligence interface, but not the slightest mention of anything financial.

When the master asked about this, the novice became indignant. "Don't be so impatient," he said, "I'll put in the financial stuff eventually."
