for i=0 to 5 document.write names(i) & " " next

There is a nested loop here. Study flow of for i=0 to 4 loop. The outer loop holds index of item that will be compared with every other, next item. For instance, when first cycle of loop begins, i is zero, and when program ends nested loop, j starts at i+1, that is, 1. So turn by turn, item at index zero is compared with every item in array. The outer array goes only till 4 because when nested loop begins, second last item will be compared with last item: j=i+1

Now we see use of a dynamically defined array, and how that array can be filled using inputbox() function.

strings is an array that is re-dimensioned whenever user types in a new string. When we declare an array, we reserve memory space for that array, that is, if we say

dim arr(20)

it means we are reserving space for twenty data items. But what if user enters just five items? The rest of space is wasted. To avoid this, we declare a dynamic array.

In above script, we have a loop whose continuance depends on user input. It keeps on loop until user enters "fin". So, when "fin" is not entered, only then dimension of array strings is increased.

When we are re-dimensioning an array, we have to use keyword preserve to preserve existing content of array. In its absence, array gets re-dimensioned, but values are lost.

Exit do forces program to come out of loop if condition that terminates it, occurs.

Third, get to know your undo and help keys. "Undo" simply reverses last action completed on computer. If you hit something that makes your document go all kerflooey, chances are you can just click "undo" (under edit menu usually) a time or two and you’ll be fine. The "help" menu is another great asset in both word processors and email programs. Rather than sitting there wondering how many times you’ve already asked your boss to explain something, just go to "help" and then type in a question like "how do I set up columns, or "how do I attach a file," and help feature will walk you right through steps. It can take you a little time, but it’s better than constantly running to your boss and looking helpless.

Fourth, make a computer savvy friend. This is so important. If there’s someone in office who seems to be really good at computer, bring them some cookies or take them to lunch and ask them if you can have a little of their time. Have them sit with you for a few minutes while you work on a document or email. Do this on a few different occasions. Chances are they’ll not only be able to answer your questions, but they’ll be able to point out some great shortcuts for you, too.

Computers don’t have to be unconquerable beasts they sometimes appear to be. Just face your fear and approach machine calmly and logically, and chances are you’ll be doing fine. The better you are at using your computer, better you’ll be at your job, and happier people will be with you!
