 pivot = vArray((inLow + inHi) \ 2)
 While (tmpLow <= tmpHi)
 While (vArray(tmpLow) < pivot And tmpLow < inHi)
 tmpLow = tmpLow + 1
 While (pivot < vArray(tmpHi) And tmpHi > inLow)
 tmpHi = tmpHi - 1
 If (tmpLow <= tmpHi) Then
 tmpSwap = vArray(tmpLow)
 vArray(tmpLow) = vArray(tmpHi)
 vArray(tmpHi) = tmpSwap
 tmpLow = tmpLow + 1
 tmpHi = tmpHi - 1
 End If
 If (inLow < tmpHi) Then QuickSort vArray, inLow, tmpHi
