MAXScript command to create PFlow_ABurn operator???

[Filip Kaczorek]

I was trying to do this with the macro recorder, I got:

Code:

particleFlow.BeginEdit()

ev1 = Event()
ev1.setPViewLocation 84 22
op1 = PFlow-ABurn()
ev1.appendAction op1
op2 = DisplayParticles()
op2.color = ev1.wireColor
ev1.appendAction op2

particleFlow.EndEdit()

Something to be expected actually.
The problem is that when I try to run the same code in the listener I get an error:

-- Type error: Call needs function or class, got: undefined

What am I missing here?

Apparently PFlow_Aburn() is not enough to create the operator - there are some parameters required?
