Step1. The following code copies a string from source to target: .data "This is the source string",0 SIZEOF source DUP(0) source ΒΥΤΕ target BYTE .code ; index register ; loop counter mov esi,0 mov esXeSIZEQE source L1: mov alusQurcelesi] target[esi], al ins esi loop L1 ; get char from source ; store it in the target ; move to next character ; repeat for entire string mov mov edx, OFFSET source call Writestring mov edx, OFFSET target call Writestring Rewrite the program using indirect addressing rather than indexed addressing. [Hint] Use OFFSET operator to save the base address of source and target.
