The following program section uses a self-holding bit to ensure that the write op-
eration is executed even if the Special I/O Unit (or Slave Rack) is busy when
WRIT(191) is executed. The type of programming is also effective when the read
operation requires more than one cycle. The Equals Flag, which turns ON when
the reading operation is completed, is used to end execution.

via CIO 0003.
