MOV AX,4c00h
INT 21h

printch Proc Near
MOV BX,0
MOV AH,0Eh
INT 10h
RET
printch EndP

End start

In such case, you will have to change the ASM convention to MASM (which is weird, cause you're using TASM):

Assembly Syntax (Toggle Plain Text) 
  1. DATASG SEGMENT PARA 'DATA'
  2. infor db "Hello world",10,12+1
  3. inforlen Equ 13
  4. DATASG ENDS
  5.  
  6. STACKSG SEGMENT PARA STACK 'STACK'
  7. mystack db 160h dup(?)
  8. STACKSG ENDS
  9.  
  10. CODESG SEGMENT PARA 'CODE'
  11.  
  12. HELLO PROC FAR
  13. ASSUME CS:CODESG,DS:DATASG,SS:STACKSG
  14. start: MOV AX,DATASG
  15. MOV DS,AX
  16. MOV CX,inforleN
  17. MOV SI,0
  18. again: MOV AL,infor[SI]
  19. CALL printch
  20. INC SI
  21. LOOP again
  22. MOV AX,4c00h
  23. INT 21h
  24. HELLO ENDP
  25.  
  26. printch Proc Near
  27. MOV BX,0
  28. MOV AH,0Eh
  29. INT 10h
  30. RET
  31. printch EndP
  32.  
  33. CODESG ENDS
  34. END HELLO

Hope this helps.
Damn it, I still dream of her....:(

The address for "Write your own" didn't work in my browser. I don't know if it was abbreviated for some reason or what? Here's the link I found for it:

Write Your Own

Alcides.

Edit: It turns out that it was abbreviated by the code mangler for display. I put the link ith text, instead of using the address itself.
