Dear List -<br>
<br>
Thanks for all your excellent help in the past.<br>
<br>
I wish to write the following type of program:<br>
<br>
#include &lt;stdlib.h&gt;<br>
#include &lt;stdio.h&gt;<br>
<br>
int main(void)<br>
<br>
{<br>
 &nbsp; &nbsp; &nbsp; &nbsp;system(prog1);<br>
 &nbsp; &nbsp; &nbsp; &nbsp;system(prog2);<br>
<br>
}<br>
<br>
If prog1 terminates with an exit value of 1, which will indicate an error condition in prog1, I do not wish that prog2 should run. &nbsp;How do I do it?<br>
<br>
Thanks again.<br><font color="#888888">
