Dear All,

I have a strange problem I am calling a perl script from another perl script using the system command.

The called perl script can exit with different values which I want to capture in the calling script. This works fine unless the called script is interrupted by ctrl-c (although I have accounted for this), instead of getting -2 (as shown below) I get 1 returned??

Any advice much appreciated.

Here is sample of my code: 

#######
# calling.pl 

eval { system ("called.pl"); };
$exit_val = $? >> 8;

#######
# called.pl

$SIG{INT} = \&exit_gracefully;

main block ...
$exit_value = 0;

exit $exit_value;

sub exit_gracefully
{
    $SIG{INT} = \&exit_gracefully;
    print "Program interrupted .. \n";
    exit (-2);
}
