desk check n.,v.

To grovel over hardcopy of source code, mentally simulating the control flow; a method of catching bugs. No longer common practice in this age of on-screen editing, fast compiles, and sophisticated debuggers -- though some maintain stoutly that it ought to be. Compare eyeball search, vdiff, vgrep.
