The thing is that "forever" has an implicit "launch". That means
that what's between the brackets is run in parallel with what
follow the closing bracket. eg. "pu"
to monkey
pd
forever [ Setsh 14 wait 1
fd 10
setsh 15 wait 1
fd 10
Setsh 16 wait 2
fd 10
setsh 17 wait 1
fd 10
Setsh 18 wait 1
fd 10
setsh 19 wait 1
fd 10
setsh 13]
pu ; <----- Runs in parallel with the code above.
end
The net effect is that "pu" is run almost immediately after the
instructions between the brackets start running.

To save an attachment to your computer, PC users should right-click (Mac users, click and hold the mouse button) on the link and then choose 'save target as' from the pop-up menu. A window will then pop up in which you can choose a location for the file.
