.

    lea dx, [ansname] ;get name     mov ah, 0ah      int 21h      mov byte [ansname], 19h ; initialize name 25 chars max      call clrscr      lea dx, [greet]     mov ah, 09h     int 21h      lea dx, [ansname+2]     mov ah, 09h     int 21h      lea dx, [greet2]     mov ah, 09h     int 21h      section .data     nextline db 0dh, 0ah, "$"    ansname times 25 db "$",0dh, 0ah,"$"    greet db "hello!",0dh,0ah,"$"    greet2 db "how you?",0dh,0ah,"$" 

1. you need write max value before calling dos service!

   lea dx, [ansname] ;get name mov byte [ansname], 19h ; initialize name 25 chars max mov ah, 0ah  int 21h 

2. setup input buffer without carriage return , linefeed codes.

   ansname times 2+25 db "$" 

3. remove carriage return , linefeed codes greet message , add space after text.

   greet db "hello! ", "$" 

4. add space before greet2 message.

   greet2 db " how you?",0dh,0ah,"$" 

5. before can print name have remove carriage return (0dh) dos appended result.

   mov bl, [ansname+1] mov bh, 0 mov byte [ansname+2+bx], "$" lea dx, [ansname+2] mov ah, 09h int 21h
