executing perl not from command prompt
If perl is set up correctly on you computer, your perl script will run when you click on it. However, if your script does not do any input from the keyboard, you probably won't know that it ran. It opens a command window, runs in it, and closes that window so fast that you do not see anything. The easiest solution is to put a diamond operator (<>) at the end of your script. This gives you a chance to see your output. Type any character, or close the window to end the script.
