Greetings, ChristieJS.

As others have duly noted, above. You really need to provide more specifics, to get anything remotely helpful, in answer to your question. Without those details, it's all quesswork, on our part. Which leaves us as frustrated, as you probably feel.

That said; generally speaking. It can be something similar to the following 

my $arg1 = ('-switcha . -switchb l -switchc');
my $arg2 = ('+15');
my $arg3 = ('filename argument');

system("/path/to/command $arg1 $arg2 | $arg3");

as you can see. The above only illustrates the semantics. Which is probably of little help with the problem you are currently wrestling with. So without further details form you. This is probably the best you'll get.

The question you ask, is already answered in the Tutorials, and more specifically, elsewhere in the Online Perl Documentation. As well as locally, on your computer (perdoc).

Best wishes.

--Chris
