I take it you mean
<Expression> FLOAT = Array[100, 1, 1]
Does your code absolutely require it? In many cases, you can use the two
interchangeably.
If you must maintain the dimensions:
IDL> dims = size(x, /dimensions)
IDL> index = 1
IDL> help, reform(x[*, *, index], dims[0], dims[1], 1)
<Expression> FLOAT = Array[100, 1, 1]
Cheers,
