in reply to backtick calls in loops

You might wish to read about how (not) to ask a question.

It's impossible for anyone to help you, for the simple reason that you're not giving your nonworking code. The following should help you post an answerable question. It might even let you ask more precisely, or find the problem yourself!

Try to write a short while loop which "calls a perl script using backticks". Does it work? Is it executed just once, or several times? If it's executed just the one time, try replacing the perl script call with a print statement. Does that execute just once? Is your loop executing more than once?

Try to find short, nonworking code, and post that. Then we might be able to help you.

[1nickt]: Ah, I see. I did read some gamer mag reviews, and yes, they lamented the fact that laptops with no discrete video card are sold as "gaming" hardware.
[1nickt]: But, they do have red keyboard backlighting! And gargoyles on the front, or words like "Maxxx" here and there. They know their demographic!
[1nickt]: True gamers don;t buy Dells, HPs, or Lenovos, I think ;-)
[ambrus]: The keyboard I bought doesn't have backlighting. I specifically had to select for that, because so many keyboards these days have lights. Why would I want lights in the keyboard? I want lights in the room, such as on the ceiling, not in the keyboard.
choroba has a small USB lamp
[ww]: ++ all (phony labels re "gaming"
[1nickt]: ambrus perhaps you know where the keys are?
