Abstract
This apparatus controls the execution and content of computer programs in equipment containing a computer by causing the transfer of program data elements, including computer instructions, with a memory means of the apparatus, wherein the selection of data for transfer is effected either by the computer, operating in a normal manner, or by the apparatus, which may shift data selection between these two selection options so that the computer ceases selection of data constituting one program and begins selecting data of another program. While data elements are being transferred with the computer, other elements of the memory means are available for examination and modification such that new programs, the content of which may depend on the results of prior program execution, can be loaded, executed, and examined without interrupting, delaying, halting, or otherwise disturbing the instruction flow of the computer equipment.
