[JASS] How do you create effects around a unit with a loop?

How do you create effects around a unit with a loop?
I can't seem to get it the only way am able to do it it by making one at a time but I seen some spells that use loops to make it but I don't see how they do it.
P.S. when I mean effects I meant like dummy units

You mean in circle?
If you do you just need a formula where to crate unit/effect.
There is a spell called "Taste of Death" that contains pretty much what are you looking for. PM me if you get any problems with it.

Edit:

• Taste of Death
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Taste of Death
  • Actions
    • Set TempLoc1 = (Position of (Triggering unit))
    • For each (Integer A) from 1 to 36, do (Actions)
      • Loop - Actions
        • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at TempLoc1 facing Default building facing degrees
        • Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
        • Unit - Add Taste of Death(dummy) to (Last created unit)
        • Set TempLoc1_Cast = (TempLoc1 offset by 50.00 towards (10.00 x (Real((Integer A)))) degrees)
        • Unit - Order (Last created unit) to Undead Dreadlord - Carrion Swarm TempLoc1_Cast
        • Custom script: call RemoveLocation (udg_TempLoc1_Cast)
    • Custom script: call RemoveLocation (udg_TempLoc1)

You change the radius by changing offset (now its 50<-really near the caster) maging it 600 or so is more in the distance.

Or if you don't want a circle, just set it to a random offset between (mindistance, and maxdistance), and a random angle (0-360)
