    Ok, I finally have the command line giving me the value returned from the command executed in the `dir` part of your code. Someone had set the PERL5SHELL and it wasn't picking up the correct command prompt to run from. But I still can't get these lines of code to work properly.

    Yes, I've checked the perl -v and it's exactly the same Running your code, I get this though C:\>perl -e "@dir=`dir`;print \"hello, $dir[0]\"" hello, It may not be perl itself, but are there any other suggestions?

      It's true, typing: 
      perl -e "@dir=`dir`; print qq{hello, $dir[0]};"

      Does print 
      hello,

      However, this is because the first line of output from the Windows "dir" command is a blank line. If instead you use 
      perl -e "@dir=`dir`; print qq{hello, $dir[1]};"

      you'll get 
      hello,  Volume in drive C has no label

      Clarification: My response only referred to the example in the parent node. I'm sorry that my response wasn't helpful. I tested my example code on 5.6.1.631 running on Windows 98, and it gave the results I stated. Perhaps I've got an incorrect assumption running around someplace.

        i --'ed your node. as ruffing stated, the first line is not blank. you might have seen this had you looked closely at my example:

        H:\perllib\Tk800.024>perl -e "@dir=`dir`;print \"hello, $dir[0]\""
hello,  Volume in drive H is Disk#1

H:\perllib\Tk800.024>

        Actually, it did work without a problem as I later posted and had nothing to do with the first line being blank (which it isn't). I've got the command line to work as stated in a later post but it still doesn't seem to be working through the web, which is an IIS5 setup.
