Chain loading is a method used by computer programs to replace the currently executing program with a new program, using a common data area (a so-called core common area) to pass information from the current program to the new program. It occurs in several areas of computing.
Chain loading is similar to the use of overlays. Like the use of overlays, the use of chain loading increases the I/O load of an application. Unlike overlays, however, chain loading replaces the currently executing program in its entirety. Overlays usually replace only a portion of the running program.

Famous quotes containing the words chain and/or loading:
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (18081855)
“Nitrates and phosphates for ammunition. The seeds of war. Theyre loading a full cargo of death. And when that ship takes it home, the world will die a little more.”
—Earl Felton, and Richard Fleischer. Captain Nemo (James Mason)
