Example – Algorithm – WebJan 20, 2016 · The 8086 int instruction generates a software interrupt. It uses a single operand which is a number indicating which MS-DOS subprogram is to be invoked. For I/O and some other operations, the number used is 21h . Thus, the instruction int 21h transfers control to the operating system, to a subprogram that handles I/O operations. WebDec 15, 2024 · 4. byte ptr indicates that the memory operand refers to a byte in memory as opposed to a word or dword. Usually, this can be omitted as the assembler can infer the operand size from registers used but there are some instructions like mov [eax],0 where the size cannot be inferred, so a byte ptr, word ptr or dword ptr prefix is needed.
