[JASS] How to clean ARRAYS

[Dreadnought[dA]]

I have a loop with an array, and I'm wondering if I need to null the values at the end of each loop or just at the end of the function.

loop
exitwhen a>speed
        loop
        exitwhen b>speed
            set q = GetHandleUnit(z,"c"+I2S(a)+"r"+I2S(b))
            set xtraU = GetHandleUnit(z,"c"+I2S(a+1)+"r"+I2S(b))
            set xtraB[1] = GetHandleBoolean(xtraU[1],"o")
            set xtraU = GetHandleUnit(z,"c"+I2S(a)+"r"+I2S(b+1))
            set xtraB[2] = GetHandleBoolean(xtraU[2],"o")
            set xtraU = GetHandleUnit(z,"c"+I2S(a+1)+"r"+I2S(b+1))
            set xtraB[3] = GetHandleBoolean(xtraU[3],"o")
            set xtraB[4] = GetHandleBoolean(q,"o")
            if xtraB[1] == true and xtraB[2] == true and xtraB[3] == true and xtraB[4] == true then
            call SetUnitOwner(q, tp, true)
            endif
            set b = b+1
        endloop
    set b = speed*-1
    set a = a+1
endloop

Don't worry about whether it's fast or not lol I know what I'm doing

You have just to clean the unit handle. It should look like this:

loop
exitwhen a>speed
        loop
        exitwhen b>speed
            set q = GetHandleUnit(z,"c"+I2S(a)+"r"+I2S(b))
            set xtraU = GetHandleUnit(z,"c"+I2S(a+1)+"r"+I2S(b))
            set xtraB[1] = GetHandleBoolean(xtraU[1],"o")
            set xtraU = GetHandleUnit(z,"c"+I2S(a)+"r"+I2S(b+1))
            set xtraB[2] = GetHandleBoolean(xtraU[2],"o")
            set xtraU = GetHandleUnit(z,"c"+I2S(a+1)+"r"+I2S(b+1))
            set xtraB[3] = GetHandleBoolean(xtraU[3],"o")
            set xtraB[4] = GetHandleBoolean(q,"o")
            if xtraB[1] and xtraB[2] and xtraB[3] and xtraB[4] then
              call SetUnitOwner(q, tp, true)
            endif
            set b = b+1
        endloop
    set b = speed*-1
    set a = a+1
endloop
set xtraU=null
set q=null

There is no need to null non handles like boolean, strings, integer or reals.

one way to clean for e.g is

local integer index = 0

loop
    exitwhen index >= 5
    set UnitArray[index] = null
    set index = index + 1
endloop

ok so if it was a unit variable instead, I would have to null each individual value like Ciebron said?
locals only have to be nulled at the end of the function and not each time you assign values to them correct?

only at the end
