good to know that.

Good Evening,

 

Here is some undocumented feature on passing parameters to the
subroutines that are fed into the ::Queue:

 

# queues are created here.....

$command = "dir /b c:\\data\\files";

$commandQueue->enqueue("&shellsub( ' $command ' )");

 

sub shellsub {

system ( shift );

}

 

The important part is to single quote $command to prevent it from being
parsed prematurely.

Single quotes garuantee that $command will be evaluated at the right
time and processed as you expected.

 

Thanks.

Igor.
