1. or break point A point of discontinuity, change, or cessation.
2. Computer Science. A point in a program at which operation may be interrupted for manual intervention.
3. break point
   1. A situation in tennis in which one more point is needed to break the opponent's serve.
   2. The point awarded in such a situation.

The location in a program used to temporarily halt the program for testing and debugging. Lines of code in a source program are marked for breakpoints. When those instructions are about to be executed, the program stops, allowing the programmer to examine the status of the program (registers, variables, etc.). After inspection, the programmer can step through the program one line at a time or cause the program to continue running either to the end or to the next breakpoint, whichever comes first.

breaking point

The point at which the field of influence of one settlement ends and that of another begins. This can be calculated according to Reilly's gravity model equation:

where d_jk is the distance of the breaking point from town j, d_ij is the distance between towns i and j, P_i is the population of town i, and P_j is the population of town j. The number of shops in each settlement may be used rather than population.
