color:#1F497D'>We say that a call is synchronous (or blocking) if it won’t
return to the caller until the task is finished. An asynchronous (or non
blocking) call returns immediately to the caller point. In that case it depends
how you’ll be notified about the completion of the started task.
Sometimes you can specify some callback or delegate function, or you have to
set up some kind of IPC (inter process communication) or periodically check
some resource.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>Hello,<br>
I have a problem about running exe from a model<br>
interpreter in GME.<br>
<br>
I run for example<br>
(void)system("C:\\WINDOWS\\NOTEPAD.EXE");<br>
from the model interpreter code.<br>
<br>
But when I run this exe, my code waits for the cmd to be closed <br>
for going on.<br>
<br>
I want my interpreter to goes on? Is there a way?<br>
<br>
best regards<br>
Vijdan<br>
