JASS Unit Groups

[Zaio]

Hi guys, i am making a spell but i am stuck on unit groups, im not really sure how to do them in JASS, everything else i know fine except groups, so could someone please make me a really simple example of setting a unit group of units in range of something, then picking a random unit in that group? Rep + credits and my gratitude.

Hope this helps:

function Group_Actions takes nothing returns nothing
    call KillUnit(GetEnumUnit())
endfunction

function Group takes nothing returns nothing
    call GroupEnumUnitsInRangeOfLoc(Your_Group, Your_Point, Your_Radius, Your_Filters)
    call ForGroup(Your_Group, function Group_Actions)
endfunction

Can you show me how to do it using X and Y reals please? locations are inefficient.

>>> GroupEnumUnitsInRange(group, X, Y, radius, filter)

function Group_Actions takes nothing returns nothing
    call KillUnit(GetEnumUnit())
endfunction

function Group takes nothing returns nothing
    local real x = Your_X_Co-ord
    local real y = Your_Y_Co-ord
    call GroupEnumUnitsInRange(Your_Group, x, y, Your_Radius, Your_Filters)
    call ForGroup(Your_Group, function Group_Actions)
endfunction
