I guess it might help to see the code that causes the error.
It is the next to last line in this code, wher the arrows point:
index = Where(Finite(vector) EQ 1, count)
IF count NE 0 THEN BEGIN
trimVector = Float(vector)
>>> trimVector[index] = vectorMin > vector[index] < vectorMax
ENDIF
VectorMin and VectorMax are scalars, the result of a MIN
and MAX function call in another part of the program.
Cheers,
David

Hey David,
It wasn't actually a pass by reference/value problem - it turns out I
was (inadvertently) trying to pass the MIN keyword as an array.

Just from that description, I would say that you were doing something
like
vector[3:5]=indgen(4)
That is, using a subscript range on the left side, and trying to
assign to it something that does not have the same length.
But given who is asking, I suspect it is not something that trivial.
