There are many things that could cause 'The instructionÕ. This will vary from one scenario to another. In most machines and consoles, this is a bug-related problem which can be fixed by debugging.

The ANI F instruction causes the assembler to look in the symbol table for the symbol F, and to build an instruction that ANDs immediate that value with the accumulator. If you meant to say ANI 0FH, that means to clear the high 4 order bits of the accumulator and to retain the low 4 order bits.
instruction register is used to store the next instruction to be executed. instruction pointer is used to store the address of the next instruction to be executed.
1byte instruction = MOV A,B 2byte instruction = MVI A,01H 3byte instruction = STA 2030H
There is one instruction set in the IA-32. Instruction set is the set of instruction that a processor can execute.
The instruction register holds a pointer to the current instruction (in working memory) while the next instruction register points to the next instruction (the first instruction immediately after the current instruction's operands). If the current instruction is a jump instruction, it can change the next instruction register, allowing the program to branch to a new instruction once the jump instruction is processed. The next instruction pointer is automatically moved into the current instruction register once the current instruction has been processed. The entire process of executing an instruction is known as the fetch-decode-execute cycle.
what is supervision of instruction
An absolute instruction is an assembly language instruction using only absolute addresses.
the number of bits required to represent an instruction of a cpu is known as length of the instruction or known as instruction.
