parallel port

I want to "read" the status of the parallel port pin #13 and based on it's status initiate an action.
Can someone tell me how to program this in the pipeline?.
I have already included a parallel port module in the pipeline and when I ground pin #13 (ie. short circuit to pin #25) I see pin #13 in the parallel module changing state. The problem is that I do not know how to use it in the pipeline.
I will appreciate any help on this.

In that same interface, do you see where the Variable dropdowns are? Just type in a word (like pin13value) and that will set that variable to the value of pin 13 (either 0 or 1). You can then use that variable in other modules.
See attached.

Great!. Thanks.
I have one more question:
Why am I getting this weird numbers?.
ie. when input #13 is not grounded, I got -1610612734
when input #13 is grounded, I got 536870914.
instead of a clean 0 or 1 respectively?.

If you set the bit number (ie. select 1 in the bit dropdown) then you should get a clean 1 or 0.

Steve.
I set the bit you recomend to 1 and still no clean 1/0.
I am getting -2147483648/0 ?
I attached a jpg file where you can see the parallel and the watch variables modules.
The variable in question is "PartePresente" (in Spanish).
What's wrong?

Jorge,
If you download the latest version this issue should be fixed.
