Abstract: A computer system performs a jump instruction routine in a program of sequentially available addressed instructions. A jump instruction which includes an operator part and a variable part is stored in at a given address. When the jump instruction is performed the variable part is used to modify the present address of the jump instruction to establish a return address and also another address to indicate where a subroutine is stored.
