Answer 1

Answer:

Assembly program that has a macro maximum that finds the larger of two numbers inputted by the user.

%include "io.mac"
.STACK 100H

.DATA
Numbers DW 3,4,5,2,6,0
msg0 db "Printing values in array",0
msg1 db "Max",0
msg2 db "Min",0

.CODE
.STARTUP
PutStr msg0
mov dx, Numbers
mov si, dx ;point to array
printValues:
cmp word [si], 0
je procedure
nwln
PutInt [si]
add si, 2
jmp printValues

procedure:
push Numbers ;push Number to stack to pass parameter by stack
call maxMeth
nwln
PutStr msg1
nwln

PutInt ax
nwln

complete:
.EXIT

maxMeth:
enter 0,0 ;save old bp and set bp to sp
mov si, [bp+4] ;point to array
mov ax, [si] ; ax holds max
add si,2 ; Increment si to next number

;Now entering loop
max:
cmp word [si],0 ; checks to see if the number is 0 and if it is, then we are done.
je finish
cmp ax, [si] ; ax holds the max . So if ax is greater than si, then dont assign si to ax.
jge increment
jmp newMax
newMax:
mov ax, [si] ; Otherwise we have a new a max

increment:
add si, 2 ;now increment si to check the next value and jump back to the main loop.
jmp max

finish: ;clean up.
leave ;pop bp
ret ;return
