  1. SI = 3 MOS Check SI = 1 Read Master Mode Register Check SI = 0 Write SI = 2 SI = 0 Terminate SI = 3 ExecuteUserProgram

  2. Read IR[4] = 0 M[IR[3,4]]…M[IR[3,4] + 9] = Next data card No Does M[IR[3,4]] = $EOJ ? Yes Abort

  3. Write IR[4] = 0 M[IR[3,4]] … M[IR[3,4] + 9] printed to the output file

  4. Terminate Two blank lines printed to output file Load

  5. Load Print header $JOB What type? Control card $DTA IC = 0 m = 0 Read next card End program $END m = 100 ? m … m +9 = card and m = m + 10 No Program card Yes Abort: Memory Exceeded

  6. ExecuteUserProgram IR = M[IC] IC = IC + 1 Examine IR[1,2] LR SR CR BT GD PD H R = M[IR[3,4]]? C = T? SI = 1 SI = 2 SI = 3 R = M[IR[34]] M[IR[34]] = R Yes No Yes IC = IR[3, 4] C = T C = F End Examine
