ABSTRACT:
Apparatus is provided for debugging a utility program without material increase in the memory capacity required. Such apparatus performs the debugging functions by using only the input-output devices as the keyboard, the console, the display, the M.C. reader which normally equip the computer. Actuation of a correction key activates the debugging program and interrupts operation of the utility program. The debugging program may be stored in a reserved portion of a ROM, or transferred into a predetermined storage area from magnetic card storage. This area is predetermined not to hold information significant to resumption of the utility program under test. A search is then made of the utility program, e.g., by addresses of the individual instructions, for the erroneous instruction. Upon discovery thereof, a correct instruction is keyed in directly from the keyboard to replace the erroneous instruction.
The debugging program records this correct instruction at the approriate addressed location in memory.
