Hi there, I'm kinda new to making asm programs and i was wondering if you could make a countdown timer where the user is asked for the input and it is displayed in countdown, lets say a max of 59 secs. I was only able to make one that counts down from 9 to 0, is there a way to input 59secs and display the countdown? Using A86 assembler btw.
Here's my code:
MAIN: JMP START MSG: DB 0A,0D,'ENTER NUMBER OF SECONDS(0-9): $' MSG1: DB 0A,0D,'-END- $' START: ;USER INPUT MOV AH,09 MOV DX,MSG INT 21H SECIN: MOV AH,08 INT 21H PUSH AX MOV AH,02 MOV DL,AL INT 21H MOV AH,02 MOV DL,0AH INT 21H POP AX MOV BL,AL MOV CL,AL DCOUNT: CMP BL,30H JE COUNTEND PUSH CX PUSH BX MOV AH,02 MOV DL,BL INT 21H POP BX DEC BL MOV AH,02 MOV DL,0AH INT 21H CALL DELAYT POP CX LOOP DCOUNT INT 20H DELAYT: ;DELAY FUNCTION USING SERVICE 2C OF INT 21H MOV AH,02CH INT 21H MOV BH,DH ; DH has current second TIMEC: ; Loops until the current second is not equal to the last, in BH MOV AH,02CH INT 21H CMP BH,DH ; Here is the comparison to exit the loop continue JE TIMEC RET COUNTEND: MOV AH,09 MOV DX,MSG1 INT 21H INT 20H
