Question

Write a program to perform the following task:
1) Read a line of text the keywords(less than 40 characters).
2) Save to the USB
3)read the file from the drive
4) clear the screen and display the text on the first line of the screen.
This programs need to be created in notepad by the Assembly language programming 8086/8088, to 80486

Answer 1

Andresfon12- i don't follow your first item - Read a line of text the keywords(less than 40 characters). What does this mean?

What are you trying to save to the USB?
When you read a file, do you mean FROM the same USB?
Will you know the USB drive name (i.e. D:)?

You'll have to figure these things out before you even consider the code to do it, but 1) doesn't make sense.

Answer 2

A) is read a line of text from the keyboard (less than 40 characters).

Answer 3

and my coding is look something like this:
PGM2CD SEGMENT

MAIN PROC FAR

;HOUSEKEEPING SECTION
ASSUME CS:PGM2CD,DS:PGM2DA,SS:PGM1SK
MOV AX,PGM2DA ; ESTABLISH ADDRESSABILITY
MOV DS,AX ; TO PGM1DA - THE PGM'S DATA SEGMENT
BUF1 DB 257 DUP (?)

BUF2 DB 257 DUP (?)
;MAIN PROCESS SECTION
MOV AH,1H ;KEY

sTART: JMP MAIN
MAIN PROC



; CALL CLEAR
INT 20H
MAIN END
;CLEAR PROC
MOV CX,30
;DISPLAY:
MOV AH,02

MOV DL,0AH

INT 21H

MOV DL,0DH

INT 21H

;LOOP DISPLAY

RET



;CLEAR ENDP

END START


MOV AH, 6;
MOV AL, 0 ;WHOLE SCREEM
MOV BH, 7;
MOV CX, 0 ;
MOV DL, 79 ;
MOV DH, 24 ;
INT 10H ;


; RETURN TO DOS SECTION

MOV AL,0 ; SET 0 AS THE RETURN CODE FOR DOS
MOV AH,4CH ; SET FOR DOS END PROCESS FUNTION
INT 21H ; CALL DOS TO END PROGRAM

MAIN ENDP

PGM2CD ENDS

;PROGRAM DATA SEGMENT

PGM2DA SEGMENT

DW
DW
DW
DW

PGM2DA ENDS

;PROGRAM STACK SEGMENT

PGM1SK SEGMENT PARA STACK 'STACK'

DW 32 DUP (?)

PGM1SK ENDS
END

Answer 4

i just need to add those task on the main process section and the segment too
