1. The function in a printer routine that separates tabulations into separate pages. 2. The function in a plotter routine that adds a fixed amount to a coordinate so that a graph being plotted will not run off the paper. Magnetometer and seismic-profiler records often are ‘‘paged’’ so that a large plotting scale can be used without requiring excessively large paper. 3. Division of data or program instructions into blocks called pages. Some of the pages may be stored elsewhere than in the computer’s rapid-access memory and brought into the rapid-access memory only as needed. In this way the effective memory can be larger than the rapid-access memory. Such storage is called virtual memory.
