Overlays  -  BBC Basic Overlay System

by Graham Crow


Overlays accompanies the Wimp Topics article in the magazine and both illustrates and simplifies the use of BBC Basic's OVERLAY system. The Overlay application on the disc can analyse a program to identify all procedure and function definitions; verify overlays to check that all procedure and function calls are defined in either the core or the current overlay; detach and save core and overlay sections from a single program; and measure section lengths.
