Suppose that you are writing an assembler for a machine that has only program-counter relative addressing. (That is, there are no direct-addressing instruction formats and no base relative addressing). Suppose that you wish to assemble an instruction whose operand is an absolute address in memory for example: LDA 100 To load register A from address (hexadecimal) 100 in memory. How might such an instruction be assembled in a relocatable program? What relocation operations would be required?
