What do you mean exactly?
Like:
<scblockedript>
for( i = 0; i <= 10; i++ )
document.write('a');
</scblockedript>
?

I'm not quite sure, but I think he wants to loop through different letters. There would be a couple of ways to do this, one would be to use a String.fromCharCode(int) function in a for loop.
String.fromCharCode(i) returns the character of the ascii value of i;
For example, String.fromCharCode(65) returns a capital A.
Stick this in a for loop, like so:
<scblockedript>
for (x = 65; x <= 81; x++)
{
document.write(String.fromCharCode(x));
}
</scblockedript>
This would print every character from capital A to capital Q.
Another way to do it would be to make a string of all the characters you wish to loop through, then loop through every character in the String.charAt(int) method. This returns the character that is number int in the string, for example
<scblockedript>
var chocka = "absdfty152634k";
for (i = 0; i < chocka.length; i++)
{
document.write(chocka.charAt(i));
}
</scblockedript>
This loops through every character in the string Chocka and prints them.
