    Oy! I downloaded and installed ActivePerl for my WinXP box. I have no clue as how to save or run files:
    1. Do I save a script, do I save it as a MS-DOS batch or a .pl doc?
    2. When I do run the .pl document, it will usually say"File not found". No, I did not misspell the shortcut. Whats wrong?
    3. When I DO run a pl script via command prompt, it will unexpectedly, immediately close after a half-second

    I have read the tutorials- dont help! Help me pleez!

    Hit it!

    First you need to make sure there is a $PATH set in your autoexec.bat

    This must include the path for your perl interpriter.

    That is why you get file not found. Next, yes it is standard to save with pl extension, but you may save it with a txt extension and run it from DOS:

    C:\>perl script.txt

    And I don't know how but you need to associate pl files with your perl interpriter, which your installer should have done for you already.

    EDIT: you do not need to set your path if you move all your perl scripts to the directory that contains your perl interpriter:


    move your script to C:\Program Files\Perl\bin
    or it might be C:\perl\bin

    this way when you type the name of your script in the DOS prompt, it will be executed with the perl interpriter because by default DOS looks in the current directory first (I think)

    Note also that AFAIK autoexec.bat cannot be manualy editied in Windows ME as it will change it back.

    the way you say 'it closes abruptly' i get the impression your typing it into the run cammand instead of from a dos prompt. if thats the case enter 'command' in the run box to get the prompt. from there call your perl script.

    if im wrong my appoligies

    aj67my, active perl addes itself to the path statement and automatically registers itself with windows to run that type of file. Unless of course he didn't reboot, in which case the path might not be changed, i don't know if it does a set path thing.

    if files with the extention .pl appear as yellow sheets of paper with a bubble in the center, its installed right.

    You will have to type cmd to get to the command prompt, and then type perl (path to file or script) to open/run a .pl file. Yes, save them as a .pl file (this is how you will start out saving practice perl progs you write in the beginning probably, and open them with notepad, of course. You can do notepad (path to .pl file) to open an existing or notepad (filenameyouchoose.pl) to open a new one with the filename you choose. I hope this helps. If you need a good book for learning, try Perl for Beginners - great book, I am working on it myself.

    well they are right.... but if you have 5.6.1 it does all the path configuration for you.but you will still have to run scripts from the DOS-promt...But if you start writing widgits(use Tk) then you can just click on the scripts without a command prompt...but here is a script to test.
    $perl = 'Power';
    print "Perl is $perl";
    but just run this code.first save it as <whatever).pl in the perl dir (c:\perl).from the command prompt type c:\perl>perl <whatever>.pl and the output should be.
    "perl is power"
    If not then we have a problem.
