These code prints the "123456789xyz" 5 times to the standard output perfectly.

Code:

format PE CONSOLE
entry start

include 'win32a.inc'

section '.data' data readable writeable
msg db '123456789xyz',0,10
format1 db '%s',0,10

section '.code' code readable executable
start:
repeat 5
       cinvoke printf,msg,format1
end repeat
invoke ExitProcess,0

section '.idata' import data readable writeable
library kernel32,'kernel32.dll',crtdll,'crtdll.dll'
import kernel32,ExitProcess,'ExitProcess'
import crtdll,printf,'printf'[/QUOTE]

How to add a newline "\n" at the format code ?

Here is my version:
Prints a newline.

Code:

format PE CONSOLE
entry start

include 'include/win32a.inc'

section '.data' data readable writeable
msg db '123456789xyz',13,10


section '.code' code readable executable
start:
repeat 5
       cinvoke printf,msg
end repeat
invoke ExitProcess,0

section '.idata' import data readable writeable
library kernel32,'kernel32.dll',crtdll,'crtdll.dll'
import kernel32,ExitProcess,'ExitProcess'
import crtdll,printf,'printf'

Btw, your code is nosense.
The exe is every time larger if you want to print more text because
you internally include all the strings five times.

Why don't you use "loop" and let it stop after 5 loops?

i think, what tmx might be asking is how to use the \r\n format specifier for printf.

i tried the following (works)

Code:

msg     db '123456789xyz',0
f1      db "%s",13,10,0

cinvoke printf,f1,msg

but i wonder why the following doesn't work

Code:

f1      db "%s \r\n",0

\r and \n is translated by C compiler, not by printf
