Hi forum, I am just wondering how I could just use the last two digits of a four digit year the user inputs. For example, I want to drop the  from  and just use the  which should be 3C in Hex so the registers would read it.
Here is my Data Segment.
NUMPAR LABEL BYTE MAXLEN DB 5 ;maximum input length ACTLEN DB ? NUMFLD DB 8 DUP(' ') BINFLD DW 0 MULT10 DW 1
And here is my code to accept ASCII characters from the user and convert them to digits. The user should input a four-digit year.
;To accept number. MOV CX,0 MOV CL,MAXLEN LEA SI,NUMFLD CLRIN: MOV BYTE PTR[SI],020H INC SI LOOP CLRIN ; MOV MULT10,1 MOV BINFLD,0 MOV AH,0AH LEA DX,NUMPAR INT 21H MOV CX,10 LEA SI,NUMFLD-1 MOV BL,ACTLEN MOV BH,0 INPUTNXT: MOV AL,[SI+BX] AND AX,000FH MUL MULT10 ADD BINFLD,AX MOV AX,MULT10 MUL CX MOV MULT10,AX DEC BX JNZ INPUTNXT ;End input.
