Hi, I've never used the alarm function as mentioned here:

http://perldoc.perl.org/functions/alarm.html

So I made a test script to see how it works.
But I couldn't get it working. Could you kindly help?
Here's the test script I wrote: 
eval {        
    local $SIG{ALRM} = sub { die "alarm\n" }; 
    alarm $timeout;        
    &do_program(1, 100);        
    alarm 0;    
}; 

if($@) {        
         print "$@<BR>\n";
}

&do_program(1, 100) will take about 2 minutes to run from start to finish.

Above script does not work because &do_program(1, 100) will continue to run from start to finish in 2 minutes regardless what I set the $timeout variable at different numbers less than 120(2 minutes).

Awaiting your wisdom to solve this problem. Thanks.

Jack
