DONT COPY OTHER CHEGG ANSWER PLEASE $.$ Make reverse code output correctly as shown in the screenshot. Base$-$Plus$-$Index Read then Write Exercise: displaying a string of characters to the monitor

This program will display a message of your choice by reading the input line then print it to the monitor.

a$.$

$2.$ Assemble the following code at the default location $($just enter $"$a $100")$

a$.$ Note only the offsets are shown as the line numbers below $($don$\text{'}$t type the offsets or comments after the semicolon$)$

MOV AX$,2000$; ;et data segment

MOV DS$,$AX

MOV SI$,1000$ ;point to storage location

MOV AH$,1$ ;read command $/108$ WAITFORLF TOP

INT $21$ ; read one char into AL $($this is $21$Hex in debug$)$

CMP AL$,0$D ;test for line feed

JE $115$ ;if line feed exit loop

MOV $[$SI$],$AL ;save character to array

INC SI ;increment byte array pointer to save next char

JMP $108$ ;JMP TO WAITFORLF TOP

MOV BX$,1000$ ;set base of stored array data

SUB SI$,1000$ ;find number of entries

MOV CX$,$SI

MOV AH$,02$ ;write command $/0120$ WRITELOOPTOP

MOV DL$,Bx$; get byte for write command

INT $21$ ;write to monitor

INC BX ;increment byte array pointer

DEC CX ;down count loop counter $($when $0$ exit$)$

JNZ $,011E,$; JUMP TO WRITELOOPTOP

INT $3$

$3.$ Save the program either mark and copy the program in windows then paste to notepad,

$4.$ Run the code by typing $"g"$ for go

The message may repeat on the same line and overwrite itself

If it does add the following code before displaying the message back to cause it to display on the next line

MOV AH$,2$ ;write monitor command

MOV DL$,0A,$; carriage return

INT $21$ ;write to monitor

Reverse the pattern that was input to the monitor so is prints out backwards in debug first then translate the code into the MASM$51$ template of part $2$

For full credit, fix the code by using the SI register for the down count loop counter instead of CX$,$ then use $Bx+SI$ to point to the data $($this will save having two down count registers in your code$)$
