Advantages of Assembly Language Having an understanding of assembly language makes one aware of − How programs interface with OS, processor, and BIOS; How data is represented in By default, a string defined with "db" is treated as part of the program's executable code, so the string's bytes can't be modified--if you write to BYTE [rdi], the program will crash with a write to H onwards. My guess is that they call them REAL instead of FLOAT, for example, just because Fortran natively supports COMPLEX numbers also, so REAL is just to signify the lack of an imaginary Problem: Write an assembly language program to transfer a block of bytes from one memory location to another memory location by using string instruction.
