Each instruction is on a separate line, with its operand (if any) on the following line. the instruction or operand may be followed by a comment which the loader will ignore. anything following an integer is a comment, whether or not it begins with //. a line may be blank in which case the loader will skip it without advancing the load address. a line may begin by a period followed by a number which causes the loader to change the load address. your program should run correctly with the any valid input files.
