Draw the call stack as it would look during the execution of the first multiply call (i.e. after the first CALL, but before the first RET). Treat start as a function with zero parameters called at the start of the program, for the purposes of drawing the call stack (even though it isn't called with CALL).

Consider this program, which defines a function multiply and then computes 2*3*4 by calling multiply twice. ' JMP start d multiply: LOAD 0,R3 LOAD -1,R4 loop: ADD R1,R3 ADD R4,R2 JGZ R2,loope MOV R3,R1 RET* el start: LOAD 2,R1 LOAD 3,R2 CALL multiply* LOAD 4,R2 CALL multiply Consider this program, which defines a function multiply and then computes 2*3*4 by calling multiply twice.
