METHOD OF CORRECTING SYSTEM PROGRAM.

摘要

A system programme stored in a floppy disc (FDo) is divided into modules such as a monitor-related module (M1), a utility module (M2), a language translation module (M3) and a post-processor module (M4) with a vector table (BT) showing each module's position. A correction data in another floppy disc (FDn) consists of a vector table (BT), a new post-processor module (M4') and a control programme (MRP). The contents of the second disc (FDn) are read into the computer's memory. Then the old post-processor module (M4) in the first disc is replaced by the new one (M4') under the control of the control programme (MRP) without changing the other modules (M1,M2,M3).
