Question
Chapter 10, Problem 10RQ
Program Plan Intro
File Copy (COP) instruction:
- The COP instruction is used to copy a block of data from one location to another for each scan during false-to-true transition.
- It does not contain any status bits.
- As soon as the instruction is executed, all the elements are copied from the source file to the destination file, each time in ascending order.
File-File (FLL) instruction:
- This instruction is used to fill the words of a file using source value.
- It can transfer the entire data file in one scan by selecting the ALL mode of control structure.
- This instruction does not contain any status bits.
File Arithmetic and Logic (FAL) instruction:
- The FAL instruction is used to copy the contents of one file from location to another.
- It performs file arithmetic and logic operations on the contents of each file.
- There are mainly six parameters and addresses which must be entered into the FAL instruction. They are as follows:
- Control
- Length
- Position
- Mode
- Destination
- Expression

Students have asked these similar questions
write the C++ instruction to close a file stream named "going".
a- Write a program which adds the values D8H, F5H and E9H. Put
the sum in file register 15H for (low byte) and file register 16H for high
byte.
b- What is the content of (low byte) and (high byte) registers in Hex?
CPU-OS Simulator has instructions like LDB (Load byte), SUB, ADD, MOV.
Using these instructions in correct form, please write the due micro-program that will
calculate the 17 - 13 + 12 and result will be loaded to register R21.
