Usually used like this:
set g = SelectByUserData(g, 15, true)

function SelectByUserData takes group g, integer d, boolean has_data returns group
     local unit u = null
     local group rg = CreateGroup()
     loop
       set u = FirstOfGroup(g)
       exitwhen u == null
       if (GetUnitUserData(u) == d) == has_data then
          call GroupAddUnit(rg, u )
