ABSTRACT:
In a method and circuit for executing an address jump command in a stored-program sequential-control system for operating machine tools or the like, an address counter is settable to a desired count and is able to count in a stepwise manner from any initial count therein and a program memory is provided which is connected to the output of the address counter and has data stored therein corresponding to each address which either is associated with the actuation of an output generator for the machine tools or the like or with the actuation of a jump command generator interrogation circuit. A first signal is generated when the data corresponding in an address is associated with the actuation of a jump command generator and the address counter is controlled when a jump command is present from the interrogated jump command generator to set the address counter to a new count which represents the jump address. This is carried out by detecting the presence of a jump command for generating a set signal, advancing the address counter to the next address in its sequence, and transferring the data associated in the program memory with this next address into the address counter by the set signal whereby the address counter receives this present jump address as its new count setting.
