#include<stdio.h>
#include<process.h>
#include<stdio.h>

void main(){
 print("calling time.bat\n");
 system("E:\TURBO\BIN\time.bat");
}

Have you tried:

system("E:\\TURBO\\BIN\\time.bat");

The \ is a preprocessor escape sequence. The character following the \ is a code. So you need a \\ to force the \ you need in your path.

I suspect yur progaram is running so fast all you see is a black screen for a split second.

Insert a getchar() after your system call. That will halt the program until you press enter. This will give you time to read what's on the screen.

Thank you so much sir it works..sir i called two .bat files together how can i make the time diffrence between both the call?

Exactly what are trying to measure? How long your .bat file takes? Or something else?

i just want to make a time delay in opening between two ".bat" files by code for eg
open "time.bat" nd after 5 sec open "sys.bat"?

There is a sleep function that will pause your program for a nuber of seconds:

sleep(5);  /*wait 5 seconds */

It is not a ANSI standard function so you may not hve access to it. If not, you can write your own sleep function:

1)Pass in the number of seconds to wait
2)clock the system clock. This is your start time
3)start a do loop
4)inside the loop clock the system clock. This is your current time.
5) stay in the loop as longs as start time+wait seconds is less then the current time.
6) return when you drop out of the loop.
