[JASS] Nulling variables quick question

[DistantHaze]

Is it a good practice to null a handle like u = unit before reassigning u to another unit (as in a loop), or is this unnecessary?

loop
set u = FirstOfGroup (g)
call RemoveUnit (u)
set u = null*
endloop

Unneeded. Only once when you're done with the variable, or in other cases when it might be practical to for other reasons.

Thank you very much!

function something takes whatever you want returns whatever you want
some locals
do whatever you want
null locals
endfunction

Tip: It doesnt mean that "you dont need to null something in a loop so you dont have to destroy something in a loop too"

[jass="The Point of Existance"]loop
set loc = Somewhere in Matrix
exitwhen wheneveryouwant
call DoSomethingWithLocation(loc)
call RemoveLocation(loc)
call DebugMessageBJ("Your Location has been Destroy3d By Triggers")
dontendtheloop[/code]

You only need to null at the end of hte function. It will leak if the variable is left pointing to a non-permament handle.
