Nothing at all?  Are you sure?

Well, the snippet below will push keystrokes.  What happens once they're 
pushed, we can only guess, as you don't show any other code.

Okay.  Assuming br contains the number of down-arrow keystrokes you want, 
this will fill zz with the correct string.  (Assuming zz is large enough to 
hold the value, and won't be padded with spaces.)

Why, why, why, why, why?  Why do you insist on adding those extra quotes?

I thought it didn't work at all?

Correct.  Repeat takes the number of characters you want to end up with, 
repeating the input value as needed, and not a count of the number of times 
you want to input value repeated.

No syntax error where?

How is zz defined?  And how, exactly, was zz assigned a value when it ends 
up with "[CDW"?  (My guess is that you passed "4" to REPEAT.)
