at 010a (12 row) its my chain HOLA
e10a 'hola',0d,oa,'$'

i'm using Windows vista HP and a intel core2 procesor

i dunno how to put the rest of the chains in the same position as the first one... i thought about an increment or printing the interruption with the chain.. plz help i dunno what to do.
and excuse my english i'm not a native english speaker i'm mexican

You need to keep the ASCII text ouside the code flow or it will be treated like code, which it isn't!

You need to modify your code as to something as follows!

MOV	AH,9		; Write String to STDOUT
	mov	DX,Hola
	mov	CX,25

prt:	int	21h		; DOS -Interrupt
	loop prt
	int	20h

Hola:	db	'hola',0dh,0ah,'$'

well thnx for the answer but i can't put the string in the dx i tried ur code and pops and error at

mov dx,hola

the error is in the string..


then try offset Hola

or use LEA or something similar!

The idea is the data has to not be in the code flow, and you need to load its address into ds:dx.

Watch the spelling!
Are you doing this in the debugger or an assembler?

If the debugger then you need to mov dx, ####
where #### is the hard coded address of the string!

in ms-dos debugger .. and i think i get it.. save the string and cal its addres in dx right?..


I'm not sure why you aren't using one of the many free assemblers available instead of the ancient 1980 DOS debugger but yes. You'll have to enter your code instructions, then in adjacent memory (or following the code) store the data and set the DX register to point at that string data in memory!


lol ty man u helped me a lot.. and i'm using the old debugger cuz the teacher said we'll be using that until we move to *nix based systems
