i am trying to run an executable file(say a.exe) which will produce a  
a.log once finish.so i create the algo below to analyze the log file.

if(a.exe exist)  
execute a.exe

```
if(a.log exist)
  analyze a.log
 end

```

end

but, my thinking is the checking for a.log exist will be done way before  
the a.exe is finished.

any workaround for my problem? i was thinking of using a delay(if can)  
though it is not so reliable…

Just invoke the process synchronously, e.g. via “system”.
