Predict the result of the following loop and
remove or not the "shiftkey-exit":

on mouseUp
  repeat with x = 1 to 20
    -- add -1 to x  -- not recommended
    add -4/3 to x -- not recommended
    put x into fld 1
    if the shiftkey is down then exit repeat 
  end repeat
end mouseUp

"step" is especially useful in that you can do
rather `complicated' subdivisions in a very simple way:

on mouseUp
  repeat with x = 1/13 to 1-1/13 step 1/13
    put cr & x after s
  end repeat
  put char 2 to -1 of s into fld 1
end mouseUp
