This debugging routine has been reduced to a minimum

operation. It is a mobile routine which can operate around

any program that leaves an extra 30 cells of memory space.

Its function is to insert break points in any given location of

the program being debugged, and to hold the contents of

AC and Link. The programmer may examine any locations

desired and then continue to the next breakpoint. It is

presently located in 140₈ -170₈, but may be easily relocated.
