The READ operation is applicable for a full procedural input file or a full procedural combined file that use data that has been externally described or is program described. The READ operation will recover from the display but there must be a format in order for any input operations to happen. This necessity can be met on a display device by preparing an output record with the 1P indicator. This is done by writing the initial format onto the device from another program, or alternatively, if the read has a record format name, by making use of the keyword INZRCD in the description of the record in the DDS.
It is necessary to use 'operand' in the name of a record format or file in order to control it. A record format name can only be used in the instance of an externally described file. If the format is different from the one that you required, the READ operation will end in error.
If a READ operation has been successful, the file will be located at the next record that has met the required criteria. If there has been an error, the file needs to be repositioned.
A multiple device file can be specified with the word 'name'. In this instance, the READ operation will do one of the following:
• Read data from the device
• Accept the first response from any device

What is timing and control in computer architecture?
Timing pulses are used in sequencing the micro-operations in an instruction. For example, when LDA instruction is executed, the memory is read operation is performed in timing pulse T1 and memory writer operation is performed in timing pulse T2. Now the combination of the signal LDA and T1 can be used as a control signal for performing read operation. Similarly, the combination of the signal LDA and T2 can be used as a control signal for performing write operation.A master clock generator is used for controlling the timing for all register in a computer system. A state of a register cannot be changed by a clock pulse until it is enabled by the control signal, which are generated in the control unit and provide control inputs for multiplexers, processor register, and micro-operations. The control organization is of two types; hardwired control and micro-programmed control.Hardwired ControlIn a hardwired control, the control signals are generated by using the collection of combinational circuits. The main advantage of the hardwired control is that, it can be optimized to produce a fast mode of operation. Whenever a change or modification is to be done in the design, then the wiring among the various components needs to be done. Micro-Programmed ControlIn a micro-programmed control, a control memory is used for storing control information which is also programmed for initiating the sequence of micro-operations. Whenever any change or modification is required in the design, it can be done by updating the micro-program in the control memory.
How does the microprocessor knows which operation to perform first read or write?
in any of the microprocessor include sequencer that sequencer send control signal to the memory and processor to do specific operation like read or write operation
How do you use a timing gun?
Connect the power leads to the vehicle battery. Connect the control lead to the plug wire on the first cylinder spark plug. With the engine running, aim the light at the timing marks to read the timing of the engine.
How do you create read operation in unix?
What exactly do you mean by a 'read operation'; the question is missing the semantics of what you want to accomplish.
What does ECU stand for?
Electronic Control Unit (ECU) controls the fuel injection system, ignition timing, and the idle speed control system. The ECU also interrupts the operation of the air conditioning and EGR systems, and controls power to the fuel pump (through the control relay). The ECU consists of an 8-bit microprocessor, random access memory (RAM), read only memory (ROM), and an input/output interface. Based on information from the input sensors (engine coolant temperature, barometric pressure, air flow, etc.), the ECU determines optimum settings for the output actuators (injection, idle speed, ignition timing, etc.).
What is the difference between reading and writing in relation to a computer storage medium?
When undertaking a write operation the read/write head usually has to use more power during a write operation as this operation must effect a change of state in the storage medium. On the read operation the read/write head merely has to detect this changed state.
What happens when an input operation attempts to read data but there is no data to read?
error reading
Does 2001 Grand am 2.4 liter have timing belt or timing chain?
They have a timing chain, and it IS a interference engine. So read-up before you jump in!
What is function of IO-M in 8085?
I/O and memory operations are differentiated by this status signal. When it is HIGH, I/O operation takes place and when LOW, memory operation takes place. This signal is combined with read/write in order yo generate I/O and memory control signals.
