PURPOSE:To quickly perform all processing operations of a test program by a least and necessary system constitution by setting previously the expected date at a pseudo channel part for each input/output instruction with a setting instruction end sending the answer data through the pseudo channel part in response to the input/output instruction. CONSTITUTION:A CPU 11 carries out a program set in a main storage 12 and sets a condition code at a pseudo channel part 13 for the answer to be given to an input/output instruction. Thus the part 13 receives a setting instruction and writes the setting data received by an input/output control processor 18 into a store means 21. Then a test program 16 is carried out. Under such conditions, the processor 18 analyzes the input/output instruction received by the part 13 and decides the type of the input/output instruction. Then an answer condition code is read out of the means 21 in response to the input/output instruction end then given in reply to the CPU 11. |
