Statu Word

Status word bits are read and written by the CPU and directly by your program statements.

As each of your instructions is processed, CPU status word bits are used according to the function of each instruction. Status word bits are used to link your instructions together and to provide immediate results and error information. Your program statements can then read status word bits and take action, if necessary.
