Реферат: In a stored programme control, interconnections of subsets of input signals can be measured in parallel with the interconnections of all input signals within a binary value processing programme and used for further processing. In parallel with the programmable processing of the bit processor (BP), an interconnection status (VKS(n)) is automatically constituted for each AND-BRACKET-ON control statement and stored in a nesting store (ST). The interconnection status (VKS(n)) is obtained by AND-interconnection from the previous corresponding interconnection status (VKS(n-1)) and from the corresponding interconnection result (VKE) present in the bit processor (BP). By means of control statements ''SZM: Set intermediate marker'' and ''L2M: Load intermediate marker'', an intermediate marker result (ZM) corresponding to the interconnection of subsets of input signals can be stored at any desired point in the programme in an intermediate marker store (ZMS) or read therefrom for subsequent processing.
