In the 8086 microprocessor, DUP (duplicate) is an assembler directive used in defining arrays or initializing data segments. It allows the programmer to specify a single value and the number of times it should be repeated in memory. For example, BYTE 5 DUP(0) would allocate space for 5 bytes, each initialized to 0. This helps in efficiently allocating and initializing arrays in assembly language programs.
