Core Display Program

A. M. Romaya, University of Oxford, Department of Physics,

This program allows the user to display, change, dump and
punch the contents of any core location by commands initiated
from the 338 display light pen and push buttons. The program
occupies locations 5000-7340 of memory field one. The pro-
gram does not set the push down pointer or the interrupt system
and hence field 0 is absolutely free for use by other programs.
It is possible to run this program concurrently with another
which uses the interrupt system. (This second program should
not use the display unless in special modified cases.)
